Comment:
The Django URLValidator is aiming to check if URLs are valid according to
official rules (RFC 1034/1035) which forbid the usage of underscores in
hostnames (read also http://www.quora.com/Domain-Name-System-DNS/Why-are-
underscores-not-allowed-in-DNS-host-names).
If you want to relax rules for your particular usage, just subclass
fields/validators and adapt them. But I don't think we should change the
default validator for broken existing URLs.
About the example you provided, see
