I switched to a paid domain in the last few months and regret not doing it sooner - it just works, and it’s nice knowing that I won’t have to reconfigure all my stuff to point at a different domain name again in the future. Price was maybe $15/year on porkbun - very much worth it imo.

I’ve also used freedns in the past and had no complaints about them, except that I think wildcard subdomains are limited to paid supporters (very cheap though) and at the time my SWAG docker image maybe didn’t support them? It’s been a while. The service was great though. Never had problems like I did with duckdns.

Question - if your domain registrar has an API to update your A/AAAA records, and your router (or other home server) lets you easily update those records via the API when your public IP changes, is there a benefit to using freedns or any other DDNS service? It seems like you don’t really need them if you own a domain.
