nslookup is more forgiving. The only legal characters in domain names are
[a-zA-Z0-9] and '-', apart from the '.'.

Apple's resolver routine in MacTCP used to support '_', but with MacTCP v
2. they dropped that support and made a big announcement to the world
saying that if a name contained an underscore, it would not be resolvable
by a Macintosh. Simple. Final. No correspondence entered into.

The squid message could be changed to "DNS lookup not possible because of
illegal characters in name".

I'm against supporting these names.
