Learn how to get a new IP address.
As an XFINITY® Internet subscriber, you’re given an Internet protocol (IP) address assigned by a Dynamic Host Configuration Protocol (DHCP) server. While not permanent, your IP address doesn’t change often. There will be times, however, when you are assigned a short-term DHCP lease, and you’ll need to release and renew your IP address.
You may have been assigned a short-term DHCP lease for a number of reasons:
A properly configured device — regardless of the length of its lease — automatically renews its DHCP lease when the current one expires. This shouldn’t cause an interruption in service.
Occasionally, you’ll have to manually release and renew your IP address. This may happen when there’s been a power outage, you’ve moved your computer, bought a new router, or reconfigured your home network. Find your operating system below and follow the steps as directed.
