edit: or does 'domain' mean 'fully qualified domain name'? (fqdn)
then 'localhost' is invalid

Regardless of the intention of this method with regard to local vs Internet domains, it would be very nice to have a way to specify what is desired. Either additional validation functions or additional arguments to say whether names without any dot separators should be valid and whether IPv4 addresses should be valid and whether IPv6 addresses should be valid.

@stevecj makes a good point. The url validation function doesn't work as expected.
