    dear anpu

    u said that the network ID of the address will be
    so as we can see that this is a class A adders so net step to do is the /19
    this mean that your Subnet mask contain 19 1's like that
    in binary
    11111111.11111111.11100000.00000000 and then u have to convert it to decimal
    it will be so this will be your target Sn-id

    then u said that u want the first subnet Ips it ok
    well it takes some time from me to calculate it but here is the full range

    in the next post
