--------------------------------------------------------------------------
RFC 2396 is an obsolete and superseded spec for URIs. DomainValidator handles
domain names, which are not URIs. Surprisingly, I was not able to quickly
locate the official syntax for domain names or IDNs, but I'm sure it's around
somewhere. Maybe RFC 5890?
Does it matter that 0021_amedia is a host name, not a domain name?
https://en.wikipedia.org/wiki/Hostname does suggest that underscores are not
allowed.
