If you work in the blogging industry, you must unlock some country-lock websites. Sometimes, it is for competition analysis, and sometimes, it is for content analysis. No matter what you want to do, a cheap residential proxy is your way to go. But what is a residential proxy?
Well,
A residential proxy is an IP address assigned to a natural home or device, making online activity appear as if it’s coming from an actual user rather than a data center.
Well, then, how does it work? Is it safe to use? Read on to learn about it.
What Is A Residential Proxy?
A residential proxy network is a type of proxy network made up of real IP addresses supplied by Internet Service Providers (ISPs). These IP addresses are linked to actual locations worldwide, either at the country or city level.
A residential proxy network is an internet tool that makes it look like you are browsing from a different home or location. It’s like borrowing someone else’s address so websites think you’re in a different place.
IP addresses are often linked to physical locations and are part of networks of various sizes. These locations can range from local areas to a global scale.
A reverse web proxy, commonly used with residential proxies, enhances security and performance by receiving client requests and directing them to the correct servers, all while hiding the client’s IP address.
Even though billions of devices connect to the internet simultaneously, their IP addresses can still reveal the device’s location. So, every time you go online, details like your browser preferences, cookies, and IP address are logged. It’s kind of like a paid VPN.
What Is The Difference Between A Residential Vpn And A Residential Proxy?
VPNs allow you to choose which country you want to appear to be browsing from. On the other hand, residential proxies make it look like the IP address genuinely comes from the country it claims to be from.
This makes residential proxies less likely to raise suspicion when using streaming services, radio, or other entertainment platforms.
What Is A Residential Proxy Used For?
Residential proxies help with tasks like accessing geo-restricted content. They also ensure secure web scraping, manage multiple social media accounts, and improve browsing privacy. That’s why it is mainly used for:
Staying anonymous: They help protect your privacy by making it look like you’re browsing from a different location.
Collecting data: Do you need to gather information from websites, like monitoring competitors or tracking prices? Residential proxies let you scrape public data without getting blocked.
Ad verification: You can check if ads on your page are legit and block any suspicious ones that might harm your business’s reputation.
Scalping: Some people use residential proxies when bypassing storefront IP blocks to hide their bots.
Managing social media: If you’re juggling multiple social media accounts, proxies let you manage them from different locations without getting flagged.
Are Residential Proxies Illegal?
Residential proxies are not illegal, but how they are used can determine their legality. Using mobile residential proxies for legitimate purposes, like improving privacy or managing multiple accounts, is generally legal. However, using them for hacking, fraud, or bypassing restrictions in ways that violate terms of service can be illegal. It’s essential to ensure you’re using them in compliance with local laws and the rules of the platforms you’re accessing.
How Does A Residential Proxy Work?
A residential proxy works by routing your internet traffic through an actual IP address provided by an Internet Service Provider (ISP) rather than using a data center IP. Here’s how it works:
Request Routing: When you request to access a website, your request is first sent to the residential proxy server.
IP Masking: The residential proxy server then forwards your request to the target website using its IP address, which appears as a genuine residential address.
Receiving Data: The website returns the response to the residential proxy server.
Forwarding Data: The residential proxy server then returns this response to you.
This process makes it look like your browsing activity is coming from the location of the residential proxy’s IP address. It helps you to hide your real IP address and improve privacy.
Types of Residential Proxy
All those talks about the benefit of residential proxy got you thinking about which type to get, right? Well, there are many types, such as:
Residential Proxies
These use IP addresses provided by Internet Service Providers (ISPs) and are linked to real residential addresses. They are useful for tasks requiring high anonymity and a genuine location, such as web scraping, ad verification, and bypassing geo-restrictions.
ISP Proxies
These are similar to residential proxies but are provided directly by ISPs. They offer high-speed connections and are generally more reliable, making them suitable for high-bandwidth activities and accessing content restricted to specific regions.
Smartproxy
Smartproxy is a popular residential proxy provider known for its large pool of IP addresses and user-friendly services. It offers rotating and static proxies for various use cases, including web scraping and managing multiple accounts.
Bright Data

A “DNS server is not responding” error means your computer system can’t find the exact websites. This happens because your computer can’t talk to the DNS server, which helps find websites.
Your computer is like a person trying to find a specific building. The DNS server is like a map that shows a building’s location. A “DNS server not responding” message is like losing your map. Your computer can’t find the website because it doesn’t know where to look.
The internet is important for our daily lives. It’s annoying when you get a message saying, “DNS server is not responding. It prevents you from accessing websites. This error message indicates a problem with the Domain Name System (DNS). The DNS is a key internet service. It translates human-readable domain names (like [invalid URL removed]) into machine-readable IP addresses. Computers use these to connect to websites.
How does DNS Work?
A DNS (Domain Name System) servertranslates human-readable domain names like techpioner.com or shotecamera.com into machine-readable IP addresses (192.168.1.1 or 172.20.0.200). This process allows users to access websites without remembering complex numerical addresses (IP Addresses). Here’s a brief outline of how DNS servers work:-
DNS Resolver (Recursor): This server receives the initial query from a user’s device and acts as a middleman, querying other DNS servers to find the correct IP address.
Root Nameserver: The first stop in the DNS query process, it directs the resolver to the appropriate Top-Level Domain (TLD) server (like .com or .net).
TLD Nameserver: This server handles the specific TLD and directs the resolver to the authoritative nameserver for the domain.
Authoritative Nameserver: The final stop provides the IP address for the requested domain name.
This entire process happens in milliseconds, ensuring a seamless browsing experience for users.
Error: “The DNS server is not responding.”
There could be a few reasons you’re seeing“DNS server is not responding.” It might be a temporary problem with your internet service or an issue with your home network equipment, such as your router or modem. Sometimes, there’s a glitch with how your computer is set up to use the internet.
There are some basic steps to troubleshoot and fix the “DNS server not responding” error:
Restart the router and modem: Turning them off for 30 seconds can often fix internet problems. It will also let them reconnect to your ISP’s DNS servers. Then, turn them back on.
Flush your DNS cache: Your device/ browser stores a cache of recent sites to speed up browsing. However, this cache can sometimes become corrupted or outdated, leading to DNS errors. Flushing your DNS cache clears temporary data from your browser/devices. It forces your device to get fresh DNS records from the server.
Try a different device or web browser: If the problem occurs only on one app, the app might be broken. Try the website on a different phone or computer to see if it works.
Change your DNS server address: Your computer usually uses your internet company’s DNS. You can change this to use Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220) instead. These might be faster.
Update your network adapter driver: Outdated or corrupted drivers can cause connectivity issues, including DNS errors. Updating your network adapter driver to the latest version may help fix these problems.
Here are some additional solutions you can try if the above steps don’t work:
Disable IPv6: It’s the latest internet protocol version. Some devices or routers might have issues with it. Disabling IPv6 on your device can help. It may be causing the DNS error.
Check your security programs: Your antivirus, firewall, or VPN might block internet access. Try turning them off to see if that fixes it.
Restart the PC in safe mode: Safe mode is a diagnostic mode for Windows that loads only the essential drivers and programs needed to run the OS. Restart your computer in safe mode. Then, try to access the Internet. This can help determine if a background program is causing the DNS error.
Troubleshoot your network connection. If thatfails, your internet connection may have a bigger problem. Call your internet company for help.
Following these steps should fix the “DNS server not responding” error. Then, you can browse the Internet again. These are general troubleshooting steps. The solution may vary by device, OS, and network. If you’re uncomfortable changing your network settings, please ask your ISP or tech for help.

Those who’ve tried containerization have seen the Docker error message. It says “cannot connect to the docker daemon at unix:///var/run/docker.sock.” Is the docker daemon running?” is an unwelcome but familiar sight. This cryptic message often starts a frustrating troubleshooting journey. It leaves developers scratching their heads and questioning their sanity. This article explores the heart of this common Docker issue. It looks at its causes and gives clear solutions to get your Docker containers running well.
Understanding the Beast: Docker Daemon and docker.sock.
Before we fix this error, we must know the key players. They are the Docker daemon and docker.sock.
The Docker Daemon: Think of the Docker daemon as the maestro of your container orchestra. It’s a background process. It’s called dockerd. It’s in charge of building, running, and managing your Docker containers. It listens to Docker API requests. It talks with your operating system to do tasks with containers.
The file docker.sock is at /var/run/docker.sock. It’s the channel between the Docker client (what you use to interact with Docker) and the Docker daemon. It’s a Unix socket file. It’s like a network socket but it exists within the filesystem. This allows for efficient local communication.
Let’s now expose the usual suspects behind this error message. More importantly, let’s explain how to catch them:
The Docker Daemon is down. The simplest explanation is that the Docker daemon isn’t running.
Check Daemon Status. Use systemctl status docker. On older systems, use service docker status.
Start the Daemon: If it’s not running, start it with systemctl start docker (or service docker start).
To avoid this issue in the future, enable the Docker daemon to start on system boot. Use: systemctl enable docker (or chkconfig docker on).
Permission Issues: The Docker client might lack the needed access to the docker.sock file. The solution is:
Add User to Docker Group: Adding your user to the docker group usually grants the required permissions. Run sudo usermod -aG docker $USER and log out and back in for the changes to take effect.
The docker.sock file might be missing or corrupted. Its permissions might be wrong. Solution:
Verify File Existence: Check if the file exists at /var/run/docker.sock.
Check Permissions: Ensure the file has the correct permissions (usually srw-rw—- owned by root:docker).
Restart Docker: Restarting the Docker daemon might regenerate the socket file if it’s missing or corrupted.
A strict firewall could be blocking access to the Docker daemon. To fix this, adjust the firewall configuration.
Configure Firewall Rules: Allow connections to the Docker daemon through the firewall. The specific commands depend on your firewall software (e.g., ufw, firewalld).
Problems with Docker installation can be caused by a corrupt or incomplete installation. These problems can lead to various issues, including this one. Solution:
Reinstall Docker. Consider reinstalling it. Be sure to follow the official instructions for your operating system.
Beyond the Basics: Advanced Troubleshooting.
If none of the above fixes the issue, there might be more subtle problems. In such cases:
Check Docker Logs. Look at the Docker daemon logs. They are usually at /var/log/docker.log or similar. They may have clues about the problem.
Verify System Resources. Check that your system has enough free memory and disk space for Docker to work.
Seek community support. Online forums and communities are dedicated to Docker. They can be invaluable for troubleshooting complex issues.
Conclusion
Encountering the “cannot connect to the docker daemon” error is frustrating. But, understanding its causes and solutions empowers you to overcome it. You can do this by checking the Docker daemon. Look at its status, permissions, and socket file. Also, check the firewall and Docker installation. This will get your containers back on track. Then, you can continue your journey into the world of containerization. Remember, even experienced Docker captains hit rough seas. Navigating these challenges separates a novice from a true Docker expert.

Two phrases that are commonly seen in .NET development are ADO.NET and ASP.NET. These concepts appear to be related, but it is important to know how they differ. The objective of this article is to explain what ADO.NET and ASP.NET do as part of the .NET framework, trace their growth paths, and provide examples of how they are used in real-life situations.
From Dynamic Web Pages to Robust Web Applications: The Evolution of ASP.NET
Let’s back up before we get into the distinction between ADO.NET and ASP.NET. Dynamic web page creation was made possible by Microsoft with Active Server Pages (ASP) in the late 1990s. Through server-side scripting in VBScript mostly, ASP allowed for dynamic content generation. However, code organization, scalability, and error handling were some of the areas where it fell short.
The year 2002 saw ASP.NET emerge offering a significant new leap forward in web development by leveraging the power of object-oriented programming (OOP) atop the sturdy base that is . NET. While the scripting of its predecessor, ASP, was loosely held together, ASP.NET brought a forefront of strongly-typed languages like C#. Hoever, With this change came the ability to reuse code, make it more maintainable and have an easier time debugging.
If you were to build a large-scale web application using ASP, your code would grow out of control fast. However, by taking an OOP approach ASP.NET dealt with this issue by allowing components to be created in such a way that they are reusable thus speeding up both development processes significantly while at the same time simplifying maintenance.
In addition, one of the most significant improvements introduced by ASP.NET was its error handling. When debugging applications in ASP, one usually has to wade through a tangle of code. But ASP.NET brought a structured exception handling system that simplifies error spotting, tracing and correction. This has made web applications more stable and reliable
Beyond Constant Connections: The Rise of Disconnected Data Access with ADO.NET
Hence, let us get to the heart of what sets ADO.NET and ASP.NET apart. ADO.NET came after ActiveX Data Objects (ADO), which were launched in 1996. ADO allowed for database interaction but did so in a connected manner i.e. it required maintaining persistent connections. Such an approach could result in performance bottlenecks especially when dealing with a large number of users.
ADO.NET introduced a new era of data access by bringing in its disconnected architecture. In other words, instead of having to keep connections open all the time, what ADO.NET does is that it retrieves data from databases, works with them locally, and then sends back any updates made. This makes scaling applications much easier since the servers do not have to bear heavy loads caused by continuously running queries against huge amounts of information stored on disks somewhere far away or fast but expensive memory like RAM.
Example: Let’s say you’re pulling product details from a database for an e-commerce site. When using ADO, if a number of people request the same information at once, the connection is kept open while the page is being built, which might slow down the server. With ADO.NET however, the details are gotten, the connection closed and the web page populated therefore in this case being disconnected will minimize the time the database connection stays active hence saving on server resources.
Illustrating the Difference: ADO vs. ADO.NET Code Comparison
To further highlight the difference between ADO.NET and ASP.NET, let’s look at a simple code example. Both snippets aim to retrieve customer names from a database.
ADO (using VBScript):
‘ Establish a connection to the database
Set conn = Server.CreateObject(“ADODB.Connection”)
conn.Open “connection string”
‘ Create a recordset and execute the query
Set rs = Server.CreateObject(“ADODB.Recordset”)
rs.Open “SELECT Name FROM Customers”, conn
‘ Iterate through the recordset and display customer names
Do While Not rs.EOF
Response.Write rs(“Name”) & “<br>”
rs.MoveNext
Loop
‘ Close the recordset and connection
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
ADO.NET (using C#):
using (SqlConnection connection = new SqlConnection(“connection string”))
{
SqlCommand command = new SqlCommand(“SELECT Name FROM Customers”, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(reader[“Name”]);
}
reader.Close();
}
This basic example demonstrates how ADO.NET, with its streamlined syntax and object-oriented approach, offers a more modern and efficient way to interact with databases.
Beyond the Basics: Higher-Level Abstractions and the Future of Data Access
ADO.NET is a great start, but developers often find themselves using Entity Framework for increased productivity because it’s a higher-level abstraction. Entity Framework (EF) is an object-relational mapper (ORM) that allows you to interact with databases using objects and relationships instead of raw SQL queries. This makes data access simpler, speeds up development, and reduces boilerplate code.
The world of data access is always changing. While ADO.NET will always be important, newer technologies and techniques come out all the time. Micro-ORMs give you a lightweight alternative to heavy frameworks; at the same time, specific use cases are driving NoSQL database adoption.
In Conclusion: ADO.NET and ASP.NET – Distinct yet Complementary
For .NET developers, understanding the difference between ADO.NET and ASP.NET is crucial: ASP.NET is used to build powerful web apps, ADO.NET is for fast and scalable data access. Even though these technologies are separate, they are used together in many .NET applications. Thus, any developer who wants to create contemporary efficient programs should keep track of changes in both fields as the .NET environment develops further.
