Dual-Stack Hosts Using "Bump-in-the-Host" (BIH)
Abstract
Bump-in-the-Host (BIH) is a host-based IPv4 to IPv6 protocol
translation mechanism that allows a class of IPv4-only applications
that work through NATs to communicate with IPv6-only peers. The host
on which applications are running may be connected to IPv6-only or
dual-stack access networks. BIH hides IPv6 and makes the IPv4-only
applications think they are talking with IPv4 peers by local
synthesis of IPv4 addresses. This document obsoletes RFC 2767 and
RFC 3338.
