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?
ZoneEdit.com has a free plan with dynamic DNS for at least one „real“ domain (domain registration not included). It‘s not the most user friendly UI but super powerful. You can pretty much add any DNS record you like.
