Would it be possible for me to make comments to other instances etc?

Solved: I can't, it would only work with a public domain.

You do realize all this is easily done with a reverse proxy + DuckDNS?

Wouldn't you need a publically available IP? DuckDNS is only for dynamic IP's that is public, yes?

Duckdns is pretty much a service that offers free domain names.. that could point to any public IP. (I have seen setups where local IPs are used just for HTTPS). So its good for instances as HTTPS can be achieved without buying domain name.

Works with anything that can open ports. DuckDNS works by pinging their service from anywhere to update the target IP for the subdomain.

Doesn't work if you are on CGNAT

See: Anything that can open ports. NAT of any kind tends to not allow opening ports.

Absolutely. However I feel like the whole thread needs extra clarification, considering the question OP posed.
Dynamic DNS isn't a magic wand in the way a Reverse Proxy over VPN is.

Yea, that is also what I thought. To bypass this, you would need something like Cloudflare Tunnels or setup a VPN on a VPS, that redirects traffic to your homeserver.
