RE: [idn] Proposed suggestions from Asia Pacific Top LevelDomain meeting

["Larry Masinter" <LM@att.com>]

RFC 2396 puts more severe restrictions on host names in URLs:

   The host is a domain name of a network host, or its IPv4 address as a
   set of four decimal digit groups separated by ".".  Literal IPv6
   addresses are not supported.

      hostport      = host [ ":" port ]
      host          = hostname | IPv4address
      hostname      = *( domainlabel "." ) toplabel [ "." ]
      domainlabel   = alphanum | alphanum *( alphanum | "-" ) alphanum
      toplabel      = alpha | alpha *( alphanum | "-" ) alphanum

RFC 2732 extends the syntax for IPv6 addresses, but otherwise still
restricts it to alphanum.

draft-masinter-url-i18n-04.txt doesn't currently address the issue.
