To configure IP addresses:
Sign into Fiber using the email and password you use for your Fiber account.
- Select Network in the upper-left corner. (If you don’t see it, click the navigation menu to display the selection.)
In the settings pane, click Advanced; then click Addresses.
The Addresses tab displays the following information for your Network Box:
Serial number. A unique number assigned to the device by Google Fiber. You can also find this number on a sticker on the bottom of your Network Box.
Router LAN MAC address. The media access control (MAC) address is a hardware address that uniquely identifies each node of a network.
Router IPv6 address. The external IPv6 address of your Network Box on the Internet.
Router WAN IPv4 address. The external IPv4 address of your Network Box on the Internet.
It also displays and allows you to change your Network Box's LAN IPv4 address, subnet mask, and the range of dynamic IP addresses you want to make available to devices that connect to your network.
To configure IP addresses for your network:
Change any or all of the configurable options on this tab; then click Apply.
If you change the DHCP address range and an IP address that was previously assigned to a device on your network is now out of range, that device keeps the IP address until it disconnects from the network or its lease expires.
