RFC 1631 The IP Network Address Translator (NAT) Export

@manual{rfc1631, abstract = {The two most compelling problems facing the IP Internet are IP address depletion and scaling in routing. Long-term and short-term solutions to these problems are being developed. The short-term solution is CIDR (Classless InterDomain Routing). The long-term solutions consist of various proposals for new internet protocols with larger addresses. It is possible that CIDR will not be adequate to maintain the IP Internet until the long-term solutions are in place. This memo proposes another short-term solution, address reuse, that complements CIDR or even makes it unnecessary. The address reuse solution is to place Network Address Translators (NAT) at the borders of stub domains. Each NAT box has a table consisting of pairs of local IP addresses and globally unique addresses. The IP addresses inside the stub domain are not globally unique. They are reused in other domains, thus solving the address depletion problem. The globally unique IP addresses are assigned according to current CIDR address allocation schemes.
