    3/. An IP address specifies the location of a host or clientin the internet.

    38. An IP address is also known as Protocol address.

    39. The IPV4 address is 32 bits long.

    40. In IPV4 classes A ! and " are #sed to represent host and network addresses

    whereas class $ is #sed for %#lticasting.

    4&. "lass ' is reser(ed for e)peri*entalp#rpose.

    42. All 0s in the host id indicates the network itself.

    43. All &s in the host id indicates the broadcast address.

    +P address '1/.*.12./

    Belon#s to class C address and

    )ea$lt s$0net !as is '**.'**.'**.2.

    51.Discuss the class field in IP address.

    If the address is given in binary notation, the first few bits can tell us the

    class of the address.

    Class A - 0

    Class B - 10

    Class C - 110

    Class D - 1110

    Class E - 1111

    When the address is given in dotted decimal notation, then look at the firstbyte to determine the class of the address..

    Class A - 0 to 127

    Class B 128 to 191

    Class C 192 to 223

    Class D 224 to 239
