We are committed to providing you the best internet experience. As the internet evolves, so do our services. Along with the industry, we are making the transition to IPv6.
Why A New Internet Protocol Is Happening
Much like letters and packages transported by the postal service, each computer or device connected to the Internet must have a unique address, called an IP (internet protocol) address. Data transported over the internet must have the addresses of the device it came from and the one it's going to. Since 1981, Internet Protocol version 4 (IPv4) has determined these addresses. There are approximately 4.3 billion IPv4 addresses, all of which have been assigned almost all of which are in use. In 2015, ARIN (American Registry for Internet Numbers) announced that IPv4 would soon be exhausted.
When you consider that there are over 7 billion people in the world, and many people have more than one connected device (smartphone, tablet, TV, etc.), it is not surprising that 4.3 billion addresses is not enough. Internet Protocol Version 6 (IPv6) replaces IPv4. This newer version of IP has more than enough addresses to serve all IP networking needs for the foreseeable future. IPv6 is therefore vital to the continued growth of existing IP networks and the creation of new IP networks.
We recognize that IPv6 is an essential technology for ensuring the growth of the Internet and meeting the needs of our customers. We also view it as a promising avenue for future innovation in networking and networked technologies. Finally, we understand that many of our customers will require IPv6 connectivity, either private or to the public Internet, and we are dedicated to supporting those needs.

We're Ready So You're Ready
Prepared for IPv6
We have ensured that you will have access the internet and your email without any change in your experience. Our national backbone and regional networks support IPv6 today. Internet transit and peering connections between other internet service and content providers are also in place. We have successfully enabled IPv6 on our foundation infrastructure delivering IPv6 connectivity to its "headends." We've also enabled IPv6 access to our customers' homes and businesses.
What Has Spectrum Done to be IPv6-Ready?Connectivity to IPv4
While IPv4 cannot support the growing address needs of the world, it's not going away immediately. We've ensured that all Internet connections through our network are capable of reaching both IPv4 and IPv6 content and that our end users have access to both.Dual Stack
We use a "Dual Stack" implementation. This means that IPv4 and IPv6 run at the same time at the network level. This approach minimizes customer impact.Transition Technology: IPv6/IPv4 Compatibility
IPv6 is not "backwards compatible" with IPv4. This will be unnecessary once IPv4 is decommissioned, which is likely to happen in the future. In the meantime, transitional technology will be used to make IPv4 and IPv6 work together.Hardware Certification
We actively participate in internet standards organizations and industry forums such as CableLabs. We have an extensive IPv6 certification program for Spectrum equipment, and we work closely with our vendors to validate that their IPv6 functionality is working properly within our network to our exacting standards.Applications
As new applications that exploit IPv6 capabilities come to market, we continue to look for new services that this protocol can bring to our customers and to improve our network.Spectrum Customer Preparation
What should customers do to prepare? The good news is, you won't need to do anything in order to continue to enjoy your existing Spectrum services. As IPv6 integration takes place, you won't notice a change in your internet experience.
