I got a homelab, at the moment I am only running some local stuff and tailscale to reach my stuff remotely.
I can use tailscales ddns, but I would like a real domain. Is there a domain registrator that works with dynamic ips? Or do I need to use a CNAME instead of A record?
It really depends on the company that you use to manage the domainās DNS. As long as they have an API to update DNS recordsā¦
For example, I can have my domain at Porkbun and have its DNS managed at Cloudflare. Cloudflare allows updating DNS records via APIā¦so thereās programs to update it. Some routers even support it.
Worst case, you can set up a service like duckdns and have your domain, via cname, point to the duck DNS subdomain.
Thereās options.
I think using the cloudflare API is the way to go. You could probably set up an internal service that translates your home routerās dyndns request to a cloudflare API call.
Only if you had root access to your router. Itās a lot easier to write or find a very simple update script and schedule it to run every now and then via crontab.
