CCNA: Implementing Network Address Translation (NAT)

Network Address Translation (NAT) is a process that allows network administrators to translate one or more IP addresses within a network to a single IP address. It is used to increase the efficiency of a network by reducing the number of IP addresses that need to be managed. NAT is most commonly used to connect multiple computers to the Internet.

NAT is typically implemented on routers, which allow multiple computers to connect to the Internet using a single public IP address. This is beneficial as it reduces the number of public IP addresses that a network administrator needs to manage. By using NAT, a single public IP address can be used to connect multiple computers to the Internet.

For example, if a network administrator has 10 computers on a network, but only has 8 public IP addresses to assign to them, NAT can be used to allow all 10 computers to connect to the Internet using the 8 public IP addresses.CCNA course in Pune

In addition to reducing the number of public IP addresses that need to be managed, NAT also provides a layer of security for the network by hiding the private IP addresses of the computers. This means that the private IP addresses of the computers are not visible to the outside world, making it more difficult for an attacker to gain access to the network.
