According to RFC 952 (DoD Internet host table specification) an
underscore is not part of the character set for host names. This
would also include the domain part. I don't know if there's an RFC
which updates this, but I've seen the problem before in this form:

http://user_name.example.net/

I could reach the site from some ISPs, but not others. At my place of
work, I got a specific error which mentioned the illegal char.
