Unless there is something peculiar about Wollongong, and I doubt it, one
sets up a subnet using the ifconfig command, it should be of the form:

	ifconfig interface IP-address netmask 0xffffff00
                                      ^^^^^^^^^^^^^^^^^^

The netmask is what determines the class of the subnet, also remember that
all the hosts you want on your subnet better be set up similarly.
