TCP option "request IPv6 connection"

Martin Rosenau

Abstract

This document describes an idea for a header option for the Transmission Control Protocol (TCP). The extension is used by dual- stack nodes to force the use of the IPv6 protocol instead of the IPv4 protocol when exchanging data over TCP. Especially if one of the two nodes is a NAT64 or NAT46 router it makes sense not to use IPv4 but IPv6 if both nodes are dual-stack nodes. This document also suggests to declare the usage of such a method mandatory for all nodes that use IPv4 addresses that will be assigned by RIRs in the future. Doing so will make it impossible to (mis-) use IPv4 addresses assigned by RIRs to ISPs for IPv4-only nodes that do not support IPv6.
