4.5.2.1
Static IP address assignment
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.
The default gateway is the routing device used to forward all traffic that is not addressed to a station within the local
subnet. Your ISP will provide you with the default gateway address. Figure 4-12 shows a default gateway address of
10.247.16.1 because this was the default gateway defined when the CLIP connection was configured.
The Hostname can be any alphanumeric word beginning with a letter and containing no spaces. The domain name is
used to in conjunction with the host name to uniquely identify the modem.
