Apple under fire for backing off IPv6 support

Carolyn Duffy Marsan | April 16, 2012
Apple Computer came under fire for back-pedaling on its support for IPv6, the next-generation Internet Protocol, at a gathering of experts held in Denver this week.

IPv6 is needed because IPv4 is running out of addresses to connect new users and new devices to the Internet. IPv6 solves this problem with a vastly expanded address space, but it is not backwards-compatible with IPv4. So ISPs like Comcast have to upgrade their routing, edge, security, network management and customer premises equipment to support IPv6. The alternative is for carriers to translate between IPv4 and IPv6 addresses, which adds latency and cost to network operations.
