I just tested it using Apple iTunes (actual IP addresses obfuscated
because to the MAC address encoded in them):

"ANNOUNCE rtsp://fe80::216:1234:567:89/2822725808 RTSP/1.0
[…]
o=iTunes 2822725808 0 IN IP4 fe80::321:1234:567:89
s=iTunes
c=IN IP4 fe80::123:9876:543:21
t=0 0
[…]"

It still uses "IP4", despite the underlying protocol being IPv6.

Regards,
Michael
