Title:
SIPNAT: a new technique for transparent interoperation of IPv4?and IPv6
Abstract:
Businesses, online service organizations, governments, and family?websites?all require global presence and continuous, on-demand availability.?Customers and clients have to be able to initiate contact with the?servers,?not the other way around. ?Unfortunately, with traditional port-mapped?NAT (NAPT), this is impossible because the translation parameters for?each flow must be established by the internal network node. ?I describe?a new proposal for enabling such incoming translations, called “source-IP?NAT” (SIPNAT), which relies on DNS to establish the required parameters?for the flow translation. ?Because of its natural fit with the typical?DNS model of application interaction, SIPNAT is transparent to existing?IPv4 and IPv6 nodes, does not require dual-stack or tunneling, and?enables connectivity even for protocols that do not use ports (e.g.,?GRE and ICMP). ?I also describe recent analytical results and?performance improvements that result from simple extraction of fields of?certain payloads.
