I'm using bind 4.9.4-P1. I looked at RFC1912 and they indeed mention
that an underscore is not standard, althought it is allowed in RFC1033,
which is not a standard :)

The people at usherb.ca tell me that they also set up an alias
www.crc-cuse.usherb.ca. I wonder why Squid also gives an error on this
one.

Finally, can someone tell me if the gethostbyname() call comes with
bind, or with libc?
