That's arguable, because of the colon. RFC 1738:

   URL schemes that involve the direct use
   of an IP-based protocol to a specified host on the Internet use a
   common syntax for the scheme-specific data:

        //<user>:<password>@<host>:<port>/<url-path>

...
    port
        The port number to connect to. Most schemes designate
        protocols that have a default port number. Another port number
        may optionally be supplied, in decimal, separated from the
        host by a colon. If the port is omitted, the colon is as well.

However, it says "is" rather than "MUST BE".
