IP version 6 is the newest version of the Internet Protocol that allows for continued Internet growth over the existing IP version 4. This article provides 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.
We have created a short video to explain the IPv6 transition. Click the button below to view it.
IPv6 addresses are 128 bit where IPv4 addresses are 32 bit.
- IPv6 address: 2001:0578:0123:4567:89AB:CDEF:0123:4567
- IPv4 address: 192.0.2.27
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 and/or IPv6 traffic at the same time.
Cox is working diligently to ensure all networks, systems, and products are fully IPv6-enabled in preparation for IPv4 address exhaustion. Cox began deployment of IPv6 on the Cox High Speed Optical backbone early in 2009 and is now in the process of enabling IPv6 throughout the remainder of the network.
Network upgrades in the markets have started and are expected to be completed by year end 2013. Residential customer trials are planned for 2013. Cox Business customer trials are currently underway.
