IP Version 6
Last Updated: Fri, 20 Mar 2015 > Related Articles
IP version 6 (IPv6) is the newest version of the Internet Protocol that allows for continued Internet growth over the existing IP version 4. View general information about this newest Internet Protocol.
IPv4 vs. IPv6
IPv4 and IPv6 addresses are not compatible. A computer configured with an IPv4 address is unable to communicate with a computer or website that is configured with an IPv6 address.
Cox Plans for IPv6
There are many IPv4 and IPv6 "transition" technologies that enable IPv4 and IPv6 host to communicate with each other. Cox has chosen "dual stack" as our transition method.
- In "dual stack", every networking device, computer, server, switch, router and firewall in the Cox network will be configured with an IPv4 and an IPv6 address, meaning "dual stacked."
- This enables Cox to process either IPv4 or IPv6 traffic at the same time.

IPv6 is not supported on all customer equipment, so in order to receive IPv6 addressing and communicate with other IPv6 devices on the Internet, the following are needed:
- A DOCSIS 3.0 cable modem, WiFi Modem, or WiFi Internet & Telephone modem. If using a standalone router, it must be IPv6 capable.
- A computer operating system, such as Windows 7, that is capable of IPv6.
Network upgrades in the markets were completed in 2013. Business customer trials are planned for 2015. Residential customers will be IPv6 enabled, starting in 2015.
