Your modem’s default IP address and subnet mask are 192.168.1.1 and 255.255.255.0, respectively. This subnet mask
allows the modem to support 254 users. Since the DHCP server issues a maximum of 255 addresses, there is not
much advantage to changing the subnet mask to increase the number of addresses. Further, remember that if you
change your modems’ IP address and you have DHCP enabled, the DHCP configuration must reside within the same
subnet.
