The Internet is in the midst of a transition, one that you may not even have been aware was occurring. All of the devices and applications connected to the Internet need a number, called an Internet Protocol (IP) address, to communicate with one another. As a result of the Internet’s explosive growth, the unique numbers in the original numbering system, called IP version 4 (IPv4), are running out. To ensure that the Internet can continue growing, a new numbering system called IP version 6 (IPv6) is being deployed.
To make this transition as seamless as possible, the two versions will co-exist for a period of time. During the transition, some Internet Service Providers (ISPs), such as Time Warner Cable, will provide both IPv4 and IPv6 addresses to their customers. This is commonly referred to as “dual-stack” service and will ensure that legacy devices, applications, and content that support only IPv4 will continue to function while IPv6 deployment continues.
However, as IPv4 address shortages become more acute, the address-sharing methods necessary to continue providing service to legacy IPv4-only devices will result in increased costs and decreased performance for those legacy IPv4-only devices, and the only way to avoid this is to move to IPv6. With some advance preparation and education, we can help to make the transition to IPv6 smooth.
Time Warner Cable was an inaugural participant in World IPv6 Launch and has exceeded the initial goal of having at least 1% of its subscribers to be IPv6-capable.
TWC has been aggressively rolling out IPv6 across its residential network and is near completion in several areas where we operate including Southern California, Texas and New York City. Deployment efforts are well underway throughout upstate New York and soon will be ramping up in the Midwest and Carolinas.
Time Warner Cable Business Class currently offers IPv6 Dedicated Internet Access (DIA) service across most of our footprint. We are currently working to enable IPv6 support on Time Warner Cable Business Class Broadband and Wideband access, starting with those customers using dynamic addressing. IPv6 service for customers that need static IPv6 addresses will be supported at a later date.
Residential customers who have a TWC-provided wireless gateway automatically will have IPv6 enabled when it’s available in their service area. A reboot of your equipment may be required to fully enable IPv6 in your home network.
Many residential subscribers who have a TWC-provided cable modem automatically will have IPv6 enabled when it is available in their service area. However, to use IPv6 in your home, any equipment that is directly connected to the modem (e.g., a router) must also support IPv6. A reboot of your equipment may be required.
Customers who provide their own cable modem should ensure that they are using one from TWC’s approved list. Customers who provide their own home router should look for those devices that support IPv6.
Customers should ensure that any computers connected to their network are running recent versions of Windows (Vista, 7, 8), MacOS (10.7+) or Linux/Unix, and have all of the latest updates applied.
When purchasing new “Internet connected” devices, such as video streaming devices, IP Cameras, sensors, and gaming consoles, you should confirm with the manufacturer that the device is IPv6-capable.
Keep your network devices updated with the latest software/firmware.
Use sites such as http://ipv6-test.com/validate.php to test whether the websites that you use are IPv6-capable, and request IPv6 support from those that aren’t.
