PfSense DHCP server returning invalid IPv6 address

  • I have enabled DNS forwarder and DHCP server is enabled for LAN. I am using Google ( and OpenDNS ( for DNS. Things were fine. Then I upgraded to pfSense 2.2.1 and something went bad. Now, if I use OpenDNS then the DHCP server assigns a bogus IPv6 address to clients along with a valid IPv4 address. The same bogus IPv6 address is assigned to all clients (::ffff: If I remove the OpenDNS entry then this issue goes away and DHCP server returns only a valid IPv4 address (as it should, I haven't enabled IPv6). Has anyone else seen this issue? How to make it go away?
