Question

What is NAT and why it is utilized in IPV4?

Answer 1

Answer:

✨. PAT (also called NAT overload) conserves addresses in the inside global address pool by allowing the router to use one inside global address for many inside local addresses. In other words, a single public IPv4 address can be used for hundreds, even thousands of internal private IPv4 addresses.

Answer 2

NAT is Network Address Translation is designed for IP address conservation.

Explanation:

• NAT has many uses, but preserving 'public IPv4 addresses' is its 'primary use'. This is achieved by 'requiring networks' to use 'private IPv4 addresses' internally and only when required to provide 'translation to a public address'.
• 'NAT adds a degree of privacy' and 'security to a network' because it hides 'internal IPv4 addresses' from 'external networks'. For one or more 'valid public IPv4 addresses', 'NAT' compatible 'routers' can be configured.
