How to configure duckdns ddns with ipv6 using ddclient?

I have selected ipv6 from the drop down option within the luci ddns window, but it does not update the ipv6 on the portal.

have no issues with ipv4.
any help is appriciated.

With duckdns you need to send your IPv6 address in the update, they cannot detect it.
Feel free to post your DDNS configuration along with a fragment of DDNS client log.

These are the settings i have it right now. on the portal i need to manual put the ipv6 address, which defeats the purpose altogether. I noticed that other ddns service (only ipv4)(freemyip and dynv6) gets updated first than duckdns, which is super flaky.

Enable the service, replace pictures with text - copy/paste the content of /etc/config/ddns and apply formatting using </> button.

i have enabled the service,


how to put text? or how do you mean?

Leave your subdomain only.

Don't do this as they do not have IPv6 connectivity.

ok now i removed the force ip version and used pattagobi only in domain field.

new issue: it works but the updated IPv6 on duckdns portal is different than what i see in the ddns overview menu.

i ran ipv6.icanhazip.com and it has different ipv6 ?? i am lost.

prefix is same but suffix is different

Please show the recent log.

That's correct as it shows what is in use by your PC, not your router.
Your DDNS client updates DNS AAAA record with your router's wan6 IP address.

Thanks andrew, i got confused with prefix and computer addresses(both temporary and permanent.)

but it is /128 wan6 which is displayed correctly in full format on duckdns.org, whereas at openwrt it is compressed form.

now i am trying to establish different ddns provider for example freemyip.com and dynv6.com. if possible please guide me?

dynv6 has some nice and unique features for IPv6 but I've got a feeling that this service is semi-dead and unmaintained.

What I can recommend is dynu.com
Please start a separate topic if you have problems with a new provider.
