Question 7

What is NAT? What is it used for?

Answer 7

NAT is network address translation.
This is used for addressing private IPv4 addresses.
With NAT, a private (local) source IPv4 address is translated to a public (global) address. The process is reversed for incoming packets. The router is able to translate many internal IPv4 addresses into public addresses, by using NAT.

Question 8
