The use of private addressing and NAT permits even fairly large organisations to make the best use of a small block of addresses allocated from the globally unique IP address space, and assists in conserving this limited Internet resource.

NAT should be familiar to network managers – it is widely deployed in large private networks. NAT is described fully in RFC1918 “Address Allocation for Private Internets”. NAT was introduced partly as a means of conserving real or public (also sometimes called 'routable') IP addresses. The deployment of NAT allows large organisations to give every computer a unique Internet address without diminishing the available pool of public IP addresses.
