Title: Dynamic Prefixes and DynDNS -> possible bug?
Post by: chris42 on September 22, 2025, 10:34:03 PM
Hi there,
I started to streamline my setup and use dynamic IPv6 hosts within alias. Next step would be moving my dyndns to opnsense. However when I try to configure this in the advanced option of the dyndns and try to enter the same content I put into the alias for the dynamic IPv6 hosts in the dyndns config, I get the error:

Entry is not a valid partial ipv6 address definition (e.g. ::1000).

Am I using this wrong or is this a bug?

Using 25.7.3_7

Kind regards
  Christian

Works for me. Did you enable IPv6 in the general settings and use the "native" backend? What exact value did you try to put in? The syntax check is a bit picky about whitespace...

Yes, IPv6 is active and native backend used.
I tried to put in "::02:5a11:22ff:fe4e:cd46" which is the exact same I used in the alias definition.

I think I got it... have to strip the prefix ID as well. Alias seems to be more forgiving than this syntax check.
