Although home networking vendors like Cisco and D-Link are adding IPv6 across their product lines, Apple appears to be the only vendor that is removing this feature in its management utility.
Home gateways are a critical class of networking gear that requires upgrading as the Internet migrates from IPv4, the original version of the Internet Protocol, to IPv6.
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.
