Hm. It's an old prefix (from 2005[1])- SO must be a temporary
PROBLem there.

Actually, the net has been enabled since 11 years (well, since 6 or 7 
with that prefix) - only our workgroup server was an old installation,
and I didn't find time to test all cross-dependencies with giving it
it's known-to-DNS AAAA record. Now it's a replacement machine with
a different OS, so everything has to be tested anyway.
