Find out whether your home network is ready for the web’s new IP.
IPv6
IPv6 is supposed to replace the old version, IPv4. Unlike IPv4, IPv6 provides a pool of nearly unlimited IP addresses. Other benefits include more efficient routing and stateless address auto-configuration.
The transition to IPv6 is expected to take some time, so IPv4 and IPv6 will coexist with one another for years.
The number of internet-enabled devices is growing rapidly. In early 2011, the Internet Assigned Numbers Authority (IANA) exhausted the global IPv4 free pool. Given this growth, it's important that enough IP address resources are available to ensure that everyone can connect to the internet.
IPv4 no longer satisfied these needs, which is why the internet community adopted IPv6.
Comcast's support of IPv6
Comcast’s IPv6 program strives to make the company’s content available over IPv6. We'll maintain support for IPv4, while adding support for IPv6. You won't need a new Comcast device when your area makes the switch to IPv6.
You only need a new device for your Xfinity Internet if:
- We determine the current device is malfunctioning, or
- You want to upgrade to a higher speed than your current device is capable of.
WiFi is IPv6 is compatible. However, it may require an upgrade to your gateway firmware or hardware.
If you have a wireless gateway (Ethernet to WiFi bridge) connected to an Xfinity Internet gateway to achieve wireless capability, the gateway may need to be replaced with one that is IPv6 capable.
