One of the most important drawbacks to IP version 4 (IPv4) is the limited number of unique network addresses; the Internet is running out of address space.

Two solutions to this dilemma are Network Address Translation (NAT) and IP version 6 (IPv6).

NAT provides a short-term solution to this problem by translating private IPv4 addresses into globally unique, routable IPv4 addresses.

IPv6 is the long-term solution. By increasing the size of an IP address to 128 bits, IPv6 increases the total number of addresses that are available. This section discusses both solutions.
