Regex valid IP address

Can anyone pls confirm is this a valid IP address validator, does it verify all the IP addresses. If not pls suggest a regex (am using JS), which validates all IP addresses

        regExp:/^((([a-fA-F0-9][a-fA-F0-9]+[-]){5}|([a-fA-F0-9][a-fA-F0-9]+[:]){5})([a-fA-F0-9][a-fA-F0-9])$)|^([+-]?(?=.d|d)(?:d+)?(?:.?d*))(?:[eE]([+-]?d+))?([a-zA-Z](([+-]?(?=.d|d)(?:d+)?(?:.?d*))(?:[eE]([+-]?d+))?[a-zA-Z])+)$|(^([a-fA-F0-9][a-fA-F0-9][a-fA-F0-9][a-fA-F0-9]+[.]){2}([a-fA-F0-9][a-fA-F0-9][a-fA-F0-9][a-fA-F0-9]))$|(^([0-9]){15}$)/,

Thanks in advance
