![]() 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. Typically, an Internet speed test provides you with upload and download speeds, which may not always provide a holistic view of your Internet quality. WiFi is IPv6 is compatible, however, it may require an upgrade to your gateway firmware or hardware. Aggregated Internet Measurement (AIM) helps you understand your Internet quality to identify scenarios that your Internet connection is good or bad for. You only need a new device for your Xfinity Internet if we determine the current device is malfunctioning, or if you want to upgrade to a higher level of speed than your current device is capable of. You will not need a new Comcast device when your area makes the switch to IPv6. Though Xfinity speed test results with Ookla garnered a median download speed rating of 236Mbps, that doesnt equate to every Xfinity subscriber getting at least 236Mbps. We will maintain support for IPv4 while adding support for IPv6. (We'll be happy to walk you through what to do in order to resolve them).Ī key aspect of Comcast’s IPv6 program is to make the company’s content available over IPv6. To tell if your computer or home network is ready for IPv6, visit our special test website, and in less than a minute we’ll tell you if there are any ‘red’ items that you need to fix. When your area transitions to IPv6, you’ll be able to see your IPv6 address there). You can view your current IPv4 address at. If I don't have a ping going I usually get address unreachable. It keeps working for about 20 seconds after I stop sending pings from the router. IPv4 will no longer be able to satisfy these needs, which is why the Internet community is adopting IPv6. If I look up the IPv6 address for, have my router ping it, and then point a browser at it I'll score 17 or 18 out of 20 depending on how long it takes the browser to fall back to IPv6. ![]() Given this growth, it is important that adequate IP address resources are available to ensure that everyone can connect to the Internet. ![]() In early 2011, the Internet Assigned Numbers Authority (IANA) exhausted the global IPv4 free pool. The volume of Internet-enabled devices is growing rapidly. Please visit the IPv6 Help Center for more information about our content and services over IPv6. The transition to IPv6 is expected to take some time, so IPv4 and IPv6 will coexist with one another for years. Other improvements include more efficient routing and stateless address auto-configuration. One of the main benefits of IPv6 versus IPv4 is that it provides a pool of nearly unlimited IP addresses. It is a protocol that’s intended to replace the current version, IPv4. IPv6 IPv6 stands for the Internet Protocol, version 6.
