@eaglw@social.linux.pizza If you don't mind using subdomains you can try https://duckdns.org/ they provide free subdomains. It's free and simple, you set the IP and IPv6 address, all sub sub domains also point to the IP and IPv6.
For example you could get eaglws.duckdns.org, set the IPs, and www.eaglws.duckdns.org would point to the same IPs.
