After 6 years of requests, Android still has no support for DHCPv6 because of one engineer

In June 2012, an owner of a Samsung Galaxy Nexus running Android 4.0.2 opened a case in Google's Issue Tracker requesting support for Dynamic Host Configuration Protocol for IPv6, otherwise known as DHCPv6, or RFC 3315, which allows for stateful address and connection configuration on devices joining an IPv6 network. DHCPv6, like DHCPv4, is commonly used in enterprise networks for connecting devices.

For the last six years — including through five new major versions of Android — that request has languished, when this week it was marked as "Won't Fix (Intended Behavior)" by Google engineer Lorenzo Colitti. Android is effectively the only platform which lacks support for DHCPv6, making the IPv6 implementation on Android incomplete.
