    Well class A,B and C are unicast addresses. I forget the range for multicast.

    Multicast addresses are class D, which have 1110 as the high order bits. This creates a range from 224.0.0.0 to 239.255.255.255 as valid multicast addresses.

    ranges are:

    Class A starts with a binary 0, with 0 (I think) and 127 reserved: 1.0.0.0 -126.255.255.255

    Class B starts with a binary 10: 128.0.0.0 - 191.255.255.255

    Class C starts with a binary 110: 192.0.0.0 - 223.255.255.255

    Class D we covered

    everything else is reserved for future use.
    There's no place like ^$
