5.2.6 NAT (Network Address Translations)
NAT (network address translations) solve the problem of sharing a single IP address among multiple computers. Without NAT, all computers must be assigned with a valid Internet IP address to get connected to the Internet; but Internet service providers provide only a limited number of IP addresses to each user. Therefore, it’s necessary to use NAT technology to share a single Internet IP address among multiple computers on local network so everyone can get connected.
