Hello.
I use IONOS as a registrar. And for setting the IP for DNS by DDNS, this is accomplished by using their API to generate a URL and then calling that “updateURL”.
On the web GUI, I see more of a username/password style. On an OpenWRT box, they have a more generic system of doing it.
To do this on IPFIRE, I’m thinking to simply setup a cron script. Any recommendations?
