Using JavaScript how would I validate an IP address "x.x.x.x" is a valid IPV4 unicast address e.g. is not 0.0.0.0 or multicast (224.0.0.0 to 224.0.0.255, 224.0.1.0 to 238.255.255.255, 239.0.0.0 to 239.255.255.255)?

When a IP-Range is written as aaa.bbb.ccc.ddd/ I need to calculate the first and the last included ip address in this range with C#.
