Traversal Using Relays around NAT (TURN) Extension for IPv6
Abstract
This document adds IPv6 support to Traversal Using Relays around NAT
(TURN). IPv6 support in TURN includes IPv4-to-IPv6, IPv6-to-IPv6,
and IPv6-to-IPv4 relaying. This document defines the REQUESTED-
ADDRESS-FAMILY attribute for TURN. The REQUESTED-ADDRESS-FAMILY
attribute allows a client to explicitly request the address type the
TURN server will allocate (e.g., an IPv4-only node may request the
TURN server to allocate an IPv6 address).
