IP Settings
The IP address is usually 192.168.1.1 but you can change it to another suitable
number (e.g. 192.168.0.1 or 10.0.0.1 or 172.16.1.1) to suit any existing network
devices you already have installed. The NetMask describes how big your network is,
the default 255.255.255.0 will allow for 253 computers and generally does not need
to be changed unless to suit existing network requirements.
Note: If you change your IP address the DHCP server in your modem will auto-
matically change the IP address range (DHCP pool) it hands out accord-
ingly.

DHCP stands for Dynamic Host Configuration Protocol. Your Modem has its DHCP
Server enabled by default. This means it will assign valid IP addresses to each
computer connected to it and will direct those computers to use the Modem as the
gateway to the Internet. Having the DHCP server enabled is the recommended
choice.
When selecting certain radio buttons you will notice that some of the options avail-
able for configuration will be greyed out. For example, when selecting ‘Unmanaged’
you will notice that all fields under IP Settings are greyed out. This means that no
settings are configurable if the interface is unmanaged.
