yes it does support it generally, but it doesn't like it in DNS
TKEY/TSIG records. :)

I'm mainly interested in how Windows server behave. Even if newer
Windows clients may support name compressed DNS TKEY records and not
choke when receiving such a packet, I'd prefer stick to actual Windows
DNS server behaviour, that's why I was asking for clarification about
actual server behaviour.
In my limited tests with Windows servers (iirc Windows 2008r2), it
didn't use name compression in DNS TKEY/TSIG recorsds.
Thanks for you help!
