10.0.0.0.1

Xfinity router uses 10.0.0.1 IP address as a default IP for identification on the network. When you receive Xfinity router and you or service technician installs it on the network it will connect to the network using 10.0.0.1 IP. It is possible that technician will change it to a different IP during install but this is not typical. If 10.0.0.1 is used then Xfinity router will assign addresses from 10.0.0.2 to 10.0.0.254 to devices on the network via DHCP protocol. Network mask 10.0.0.1/8 will be used.
