I guess we need to make sure we have similar text in IRI.
BTW Roy, when can we expect your revised RFC2396 text to move ahead? IRI
has a dependency on it.

Yes, but we can't assume that the last domain is a TLD.

Yes, it says that in the text describing the rule:
The production for host is ambiguous because it does not completely
distinguish between an IPv4address and a hostname. Again, the
"first-match-wins" algorithm applies: If host matches the production
for IPv4address, then it should be considered an IPv4 address
literal
and not a hostname.
All of our attempts to disambiguate within the grammar itself did not
work because, without a trailing ".", there is no way to know which is
the TLD.
