1.  What subnet mask should UNI change to and use if they want to
    have up to 50 different subnetworks in the uni.edu domain?

    Note:  UNI network address is 134.161.0.0 for the class B network.

2.  How many computers could be on each subnet for UNI, given the above
    subnet mask that you developed?

3.  Answer questions #1 and #2 for UNI wanting to have up to 300 different
    subnets here in the uni.edu domain.

4.  Suppose that the subnet mask for the middleearth.com domain is:

    255.255.240.0

    Group all of the following IP numbers for the named computers
       into groups that are on the same subnet.

    144.154.31.44    Merry.middleearth.com
    144.154.16.2     Aragorn.middleearth.com 
    144.154.16.3     Gimli.middleearth.com
    144.154.220.111  Frodo.middleearth.com
    144.154.100.111  Bifur.middleearth.com
    144.154.213.111  Bilbo.middleearth.com
    144.154.125.111  Bofur.middleearth.com
    144.154.223.111  Gollum.middleearth.com
    144.154.111.111  Strider.middleearth.com
    144.154.208.222  Gandalf.middleearth.com

    144.154.19.4     Boromir.middleearth.com
    144.154.244.244  Sauron.middleearth.com

    You can just mention the computer name when you do the grouping,
    and avoid writing the .middleearth.com every time.
