DHCPv6 in Lion
I mistakenly wrote that Mac OS 10.7 (Lion) could not support DHCPv6 client configurations. Some friends told me that they have tested Lion and confirmed that DHCPv6 can be fully supported. With this good news, all the latest common PC OS (OSX, Windows 7 and Linux) can support DHCPv6. On a further thought, OSX and Linux have better support of IPv6 configurations than Windows 7 as Windows 7 is still lacking RDNSS as of today. Windows 7 definitely needs to catch up.
