    I need help trying to figure this out. I know the class, but i have no idea how to tell the default subnet mask or invalid or private ranges







    Identify which class the following IP addresses are in and the default subnet mask. If an address is invalid, identify that. Also identify the addresses that are part of private ranges.
    a. 182.158.201.1


    b. 15.25.35.45


    c. 150.15.150.100


    d. 222.240.200.244


    e. 172.22.20.2


    f. 177.225.325.1


    g. 235.10.20.30


    h. 10.10.10.10


    i. 100.100.100.100


    j. 200.100.50.25



    k. 192.167.10.10


    l. 1.2.3.4



    m. 191.191.191.191

    You need to at least attempt your homework before you are going to see help here....

    Give your answers, tell us why you think they are that.

    Homework? Wikipedia is verbose about networks, if the study material was not enough.

    Yeah if this is a networking class, were not going to do your homework for you. The correct answers are definitely available on most network internet sites. I hope this is a beginning level network class. I agree with jack, give us something and we can provide helpful hints but thats it.

    if those IP addresses don't have subnet masks associated with them, I'd assume classful addressing and just use /8 /16 /24 subnet masks

    determining private IP addresses shouldn't be hard

    His directions indicate to determine the default subnet for the addresses, which if you can figure out which class of address it is, each one has a default subnet with it. I'm surprised their still teaching classful network design. I've been doing Classles for a few years now. I guess it's still relevant to atleast know the basics though.

    The bit pattern in the first octet for each class is as follows:

    A = 0xxxxxxx
    B = 01xxxxxx
    C = 10xxxxxx

    Where "x" = don't care

    Figure it out yourself
