I want to achieve that only the AAAA record gets updated by my FRITZ!Box (fritzhelp.avm.de). There should be no A record set.
In all strings I used on the FRITZ!Box DynDNS, both the A and the AAAA records get constantly updated.
I already tried different update url based on the deSEC documentation (Configuring your dynDNS Client — deSEC DNS API documentation) however it looks like both records are always updated.
Here’s an overview of what I’ve tried so far:
Even when I tried:
the A record gets an update and is not deleted as written in the documentation.
What am I doing wrong? Any ideas?
Thanks in advance!
