JS 验证:

ipv4地址验证：

function queryDev(ip){var exp=/^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/;var flag = ip.match(exp);if(flag != undefined && flag!=""){   return true;} else {  return false;}}   验证IPV6地址：

function queryDev(ipvalue){  var isIpv6 = false;if(ipvalue.match(/:/g).length<=7&&/::/.test(ipvalue)?/^([\da-f]{1,4}(:|::)){1,6}[\da-f]{1,4}$/i.test(ipvalue):/^([\da-f]{1,4}:){7}[\da-f]{1,4}$/i.test(ipvalue)){	    isIpv6 = true;	}if(isIpv6){   return true;} else {  return false;}}
