There are three types of NAT translation. In this lesson, we will explore the types of NAT. The main types of NAT translations are Static address translation (static NAT), Dynamic address translation (dynamic NAT) and Port Address Translation (PAT). Static NAT Static NAT translation is also known as one to one NAT. Static NAT translation… Read more

As discussed before, That NAT translates Private IP addresses into public IP addresses. So in the process of translation, there are different operations involve and understanding each of them requires understanding NAT terminology. Therefore before understanding NAT in details, it is important to understand basic NAT terminology. In a NAT terminology, the inside network is
All public IPv4 addresses must be registered with a Regional Internet Registry (RIR). The registered holder of a public Internet address can assign these addresses to a network device. There is a maximum of 4.3 billion IPv4 addresses available. Still, with the increase of personal computing and the beginning of the World Wide Web, it

We can configure the stateful DHCPv6 server, similar to a stateless server. The difference between stateless and stateful is that a stateful server also includes IPv6 addressing information similar to a DHCPv4 server and obtains the state of the DHCP. Similar to stateless DHCPv6, we need to enable unicast routing. The command ipv6 unicast-routing enables
Before a stateless DHCPv6 server is configured on the Cisco router, it is important to enable IPv6 unicast routing. The unicast routing is not necessary for stateless DHCPv6 servers, but it is required for RA messages due to using of ICMPv6. In global configuration mode, we can enable the IPv6 unicast routing using the “ipv6
Bothe of the stateless and stateful DHCPv6 operation are started with an ICMPv6 RA message from the router. The RA message may have been periodic or solicited by the device using an RS message. The devices start client and server communication when stateless or stateful DHCPv6 is indicated in the RA message. The DHCPv6 operation
Remember that we already discussed the introduction of the SLAAC and DHCPv6 in Router Advertisement (RA) messages. Now, we will briefly discuss both SLAAC and DHCPv6. Recall that the router sends a Router Advertisement (RA) message. The setting of the Router Advertisement (RA) message decides whether a client can obtain its IPv6 address information automatically
Troubleshoot DHCPv4 problem is the most important topic because of the importance of DHCP services. It is the most important service for a small, medium and large network. In this article, we will take a look at several common DHCP errors and their solution.DHCPv4 failure occurs due to multiple reasons, such as problem in operating
In some cases, we need a router to be configured as DHCPv4 clients just like a client computer. But this method is not recommended for routers in an internal network. The dynamic addressing is extremely useful for routers that connect to the Internet through an ISP. We can simply connect a router using with just
