IT pros blast Google over Android’s refusal to play nice with IPv6

DHCPv6 is an outgrowth of the DHCP protocol used in the older IPv4 standard – it’s an acronym for “dynamic host configuration protocol,” and is a key building block of network management. Nevertheless, Google’s wildly popular Android devices – which accounted for 78% of all smartphones shipped worldwide in the first quarter of this year – don’t support DHCPv6 for address assignment.
