IPv6 PD and local DNS registration


  • I take full advantage of the 'register static DHCP entries in DNS' feature for IPv4.
    I would like to do something similar for IPv6.

    I know this is somewhat more difficult as the PD from my ISP could (and does) change. And also since hosts are auto assigning an address using EUI-64 there isn't really any static DHCPv6 config to speak of. I would love to get a static /64 from my ISP but that isn't likely. So some dynamic solution will have to work.

    Is there a way to do this? I'd like for my internal hosts to start talking via IPv6 where possible.


  • Not to use with public global prefix for that, use local IPv6 (FC00:) ?

    If you want static ipv6 just get a tunnel from hurricane electric.  They will give you a /64 or if you want a /48 even..  Now you sure don't have to worry about your PD changing whenever..

    I run static /64 on a couple of my segments and and even have /64 for my openvpn connection so they can get ipv6 as well.  You will find using a tunnel is much easier then trackers and not quite ready for prime time isp deployments of ipv6 ;)

    Hopefully the ability to use DHCPv6 server with interfaces that are tracking another for IPv6 will be coming in version 2.3… that's likely still a ways off though. There will be lots of big changes in that version.

    This won't help for EUI-64 addresses, but if you opt to run IPv6 in a "Managed" way (no SLAAC), then anything that supports DHCPv6 will go that route, while anything else won't use IPv6 (i.e. Android). This is an option that would (hopefully) also be available for interfaces that are tracking IPv6.
