IP version 6 (IPv6) is the newest version of the internet Protocol that allows for continued Internet growth over the existing IP version 4. Cox is working diligently to ensure all networks, systems, and products are fully IPv6-enabled in preparation for IPv4 address exhaustion and a gradual adoption of IPv6 by the Internet at large. To manage this migration, Cox has established an IPv6 Migration Program so that when the IPv4 addresses are exhausted, we will continue our business operations without interruption.
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.
