Sheng Yang reopened CLOUDSTACK-3533:
------------------------------------


According to: http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2013q2/007077.html

Simon(the author of dnsmasq) claimed that dhcp_release didn’t support IPv6 lately. Simon also said there are some bugs in the early dnsmasq releases.

I need to check with Simon about if we can use dhcp_release on ipv6 address.
