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;
}
}
<input type="text" name="iporname" id="iporname" style="width:80px;" value="" />  
<input name="Submit" type="button"  value="验证IPV4" onclick=alert(queryDev(iporname.value)) style="width:80px"/> 

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;
}
}
<input type="text" name="iporname" id="iporname" style="width:80px;" value="" />  
<input name="Submit" type="button"  value="验证IPV6" onclick=alert(queryDev(iporname.value)) style="width:80px"/>
