Question

Fill in the blank. The process that a wireless router uses to translate a private IP address on internal traffic to a routable address for the Internet is called?

Answer 1

Answer:

Network Address Translation (NAT)

Explanation:

With the aid of Network address translation(NAT), the IP addresses of a particular local network are translated or mapped into a single or multiple global or public IP addresses. Therefore, a wireless router could use NAT to translate its private IP address on internal traffic (network) to a routable address for the internet.

With NAT, businesses can use many internal IP addresses since they are just for internal purposes and will be eventually converted into a single or a few multiple routable IP addresses.

Three types of NAT are possible:

(i) Static NAT : There is a one - to - one mapping between private IP addresses and routable (public) IP addresses. One private IP is mapped to one public IP address.

(ii) Dynamic NAT : There is a many- to - many mapping between private IP addresses and routable (public) IP addresses. Multiple private IPs are mapped to many public IP addresses.

(iii) Port Address Translation (PAT) : Many - to - one relationship between the private IP addresses and public addresses. Many private IP addresses can be mapped or translated into a single public IP address. This type of NAT is also called NAT overload.
