Source note · IPv6 for voice and UC platforms
SDP (RFC 8866) defines exactly two address types, IP4 and IP6, used in both the origin (o=) and connection (c=) lines with network type IN; an IPv6 media address therefore appears as c=IN IP6 followed by the address.
Checked 2026-10-02
This memo only defines 'IP4' and 'IP6', but other values MAY be registered in the future.
