Introduction

Find out whether your business network is ready for the web’s new Internet Protocol.

IPv6 stands for the Internet Protocol, version 6. IPv6 is replacing the legacy version of the Internet Protocol, IPv4 (Internet Protocol version 4) as the dominant protocol in use on the Internet today. One of the main benefits of IPv6 versus IPv4 is that it provides a pool of nearly unlimited IP addresses. Other improvements include more efficient routing and stateless address auto-configuration. The transition to IPv6 is happening now, however, in some cases a full transition to IPv6 is expected to may take some time, so IPv4 and IPv6 will coexist with one another for years.

The volume 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 is important that adequate IP address resources are available to ensure that everyone can connect to the Internet. IPv4 is no longer able to satisfy these needs, which is why the Internet community has been aggressively adopting IPv6.

To tell if your computer or business network is ready for IPv6, or if you wish to view your current IPv4 and IPv6 addresses (provided you have enabled support for both), you can visit our special test website. In less than a minute we will tell you if there are any ‘red’ items you need to fix. We will be happy to walk you through what to do in order to resolve them.

Comcast's support of IPv6

A key aspect of Comcast’s IPv6 program is to make the company’s content available over IPv6, as well as to enable IPv6 connectivity across all broadband and Internet products. Our content will maintain support for IPv4 while adding support for IPv6. In general, you will not need a new Comcast device to take advantage of IPv6. You may, however, be required to enable IPv6 on your own equipment.

IPv6 and your Static IP(s)

To date, Comcast has launched dynamic and static IPv6 support for all Business Internet customers. The static IPv6 addresses are included in any IPv4 lease and those addresses can all be found by logging in to  My Account
