To set up a local workgroup around the modem, you can use the private IP
address range of the modem. Allocate IP addresses to each PC and make sure all
addresses are unique (figure 33).

In figure 33, the IP class B address is used (172.16.x.x.). The 10.x.x.x
IP addresses could also be used.
If you have an existing workgroup, consider integrating the modem in this
network. Simply change the IP address of the modem to a value that falls within
the local network range.
