Here's a partial one (it won't work when you mix hex and octal in dotted notation, nor will it work with things like 8.8.2056):^((?:(?:\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])\.){3}(?:\d|[1-9]\d|1\d{2}|2[0-4]\d|25[0-5])|(?:\d|[1-9]\d{1,8}|[1-3]\d{9}|4[01]\d{8}|42[0-8]\d{7}|429[0-3]\d{6}|4294[0-8]\d{5}|42949[0-5]\d{4}|429496[0-6]\d{3}|4294967[01]\d{2}|42949672[0-8]\d|429496729[0-5])|0x[0-9a-fA-F]{1,8}|(?:0[1-3][0-7]{1,10}|0[1-7]{1,9}))$
