            // Author: Diego Perini
            // Updated: 2010/12/05
            //
            // the regular expression composed & commented
            // could be easily tweaked for RFC compliance,
            // it was expressly modified to fit & satisfy
            // these test for an URL shortener:
            //
            //   http://mathiasbynens.be/demo/url-regex
            //
            // Notes on possible differences from a standard/generic validation:
            //
            // - utf-8 char class take in consideration the full Unicode range
            // - TLDs have been made mandatory so single names like "localhost" fails
            // - protocols have been restricted to ftp, http and https only as requested
            //
            // Changes:
            //
            // - IP address dotted notation validation, range: 1.0.0.0 - 223.255.255.255
            //   first and last IP address of each class is considered invalid
            //   (since they are broadcast/network addresses)
            //
            // - Added exclusion of private, reserved and/or local networks ranges
            //
