DynDNS for IPv4 and IPv6



  • Hi,

    I have the issue that my DNS provider offers a single URL to update my records:
    https://dyndns.inwx.com/nic/update?myip=<ipaddr>&myipv6=<ip6addr>
    The problem here is if I create a "Custom" and "Custom (v6)" DynDNS client entry the last one called will be the valid one.
    This means that if IPv6 updated last I wont be able to reach the system from most places.

    It would be really nice to have a "Custom (both)" option which offers %IP% and %IPv6% or so.
    Or would you have an alternative solution?

    Greetings



  • @no

    Why do you need dynamic DNS for IPv6? Your prefix should be stable, so you don't need a dynamic DNS for it. Just use static config.



  • no, not really

    with every pppoe reconnect i get a new /56 with prefix delegation, so a static config wouldn't help



  • @no

    Do you have Do not allow PD/Address release set?



  • @JKnott

    doesn't seem to help



  • Well, first, rebuild the check-list you use when you market for a DNS provider and ISP.
    Who is your ISP ?

    True, dyndns is often IPv4 only, which permits you to call home when your WAN IPv4 changed again.
    Having a random /56 for IPv6 is even less fun.

    What about creating a
    ipv4.your-dynd-dns.tld for IPv4
    and
    ipv6.your-dynd-dns.tld for IPv6 ?

    Or, what I did : I use the Pro version of a box, of Franc's biggest historical operator. Pro means : big, slow, black, supports phone ( ?? ) and TV ( ????) (we are a companies with 8 outside lines, a fax line - soon to be abandoned) .... and this box doesn't know what IPv6 is ....
    So I decided years ago to use tunnel.he.net and never regretted it. I'll move away from them when the day I find a local ISP that offers the same IPv6 facilities. I guess I will have to transmit that mission to the next generation.

    Today, I can access my Syno Diskstation NAS using a hostname using IPv6 from all over the world - no need for dyndns because he.net never changes the /48 pool.
    And the best part : no NAT needed ☺

    Telekom / Germany

    and

    With a limited number of hosts that doesn't really workout and moving a hole set of domains somewhere else isn't what I'd like to do besides splitting them up

    I don't need NAT here either, but I guess he.net won't be routing 100 MBit/s and above(?) and if so not with the latency(?)

    routing 100 MBit/s and above(?) and if so not with the latency(?)

    Can't tell. It maxes out for me, but my ISP gives my 22Mbits/sec down, 2,2 Mbits up ....
    It's free to try, though.
