I’m currently planning to use dynamic DNS instead to assigning the relay ip directly into the pool registration certificate , is there any good free services for doing so ?
I used noip.com for a while. It was free and worked fine.
I am using https://freedns.afraid.org/
I worked around the issue by using a Hybrid Cloud Setup. (1 Relay + 1 Validator) at home. 2 Validators in a VPS. The home instances are connecting to the cloud instances through Wireguard VPN with persistent keep-alive. That way they are also reachable back by the cloud machines. Just to bring up a potential alternative. For me this made more sense because I anyways needed / wanted multiple relays and hosting them in the same location does not make a lot of sense.
Thanks a lot guys for the help
