Abstract

Network Address Translation (NAT) and Network Address and Port Translation (NAPT) are widely used to separate networks and share IPv4 addresses. They're valuable tools for network administrators and help with the imminent exhaustion of IPv4 address space and the transition to IPv6. This article surveys recent standardization efforts in this area.
