JavaScriptによるホスト判定とかも出来る予感。

//http://www.tohoho-web.com/js/location.htm
javascript:alert(location)
// url http://[host]/[path]?[cgi]
javascript:alert(location.host)
//[host][:port num]
javascript:alert(location.hostname)
//[host]
javascript:alert(location.protocol)
// http: ftp: 

javascript:(function()
      {if(location.host==location.hostname)
                {alert("ポートはデフォルトです")}
            else{alert(location)}})();
