According to my reading of RFC 1123 it is allowed, and IDNA depends on it
being allowed. The normative text says that anything that isn't a dotted
quad IP address should be treated as a domain name. It's probably sensible
to forbid all-numeric TLDs, but it isn't necessary to forbid mixed numeric
/ alphabetic / hyphenated TLDs.
