How about "_at_" - I think a leading and trailing underscore will be very

Ever seen a MicroSoft AD "SRV" dns query? Try something like:
"_gc._tcp.Default-First-Site._sites.win.ccad.uiowa.edu."
Havn't seen one that contains leading and trailing underscores, -yet-.
The previous comment was about hostnames. An underscore is not a
valid character for a hostname. The example you gave is not a hostname.
