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.
Option | Description |
Unmanaged | Interface is ignored. |
Obtain an IP Address automatically | Interface will be allocated an IP address |
| by a DHCP server. |

| by a DHCP server on your network. |

| face by a DHCP server on your network. |
Release button | It is possible to release the IP address |
| by clicking the Release button. |
