Technical Summary
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 draft obsoletes RFC 2767 and RFC
3338.
Working Group Summary
The primary point of earlier contention was with respect to whether
this NAT46-in-a-host could be placed behind a NAT64 and achieve NAT464.
The WG consensus was that that case should be disallowed, and the
present document reflects that consensus.
Document Quality
This document obsoletes two previous RFCs on implementation, and
updates them based on implementation experience. At least one
implementation is in progress for the new document, and others
are expected.
