Configure DHCP Settings on your Technicolor C1100T modem

DHCP Settings allow you to edit the DHCP settings that define the LAN addressing parameters for your modem to allocate IP addresses to LAN devices.

NOTE
: CenturyLink recommends that you keep the default settings for the LAN IP Address. Changes to this feature will reset some of the other settings on the modem. Do not proceed unless you understand the technical impacts of changing this feature. The default IP addressing values are:
  • DHCP Server: Enable
  • Modem IP Address: 192.168.0.1
  • Beginning DHCP Server Address: 192.168.0.2
  • Ending DHCP Server Address: 192.168.0.254
  • Subnet mask: 255.255.255.0
Modem Advanced Step 1-3

1.  Connect a device, such as a computer or tablet, directly to your modem using the Ethernet cable (usually yellow).

2.  Open a web browser and type http://192.168.0.1 into the web address field.

3.  Log in to your modem's settings (Modem GUI) using the Administrator Username and Password, then select "Apply." Unless you have changed the default settings, you can find the login information on the modem's sticker.
