Greetings,
my current ISP refuses to provide me a static IP and they also blocks incoming connection to my ipv6 so I can’t host services on just ipv6 too. I will be changing my ISP when the plan expires.
without public IP I can host my own IRC bouncer but I would like to know what else can I self host? Thanks in advance!
You can self host anything like this, all you need is buying a domain and set something up like DynDNS which updates the entry of the domain with your new IPv4 as soon as it changes.
I would recommend to not open your services to public, but set up a wireguard (or other VPN) endpoint in your home, which you then use to access all your services.
I think, an alternative to that would be some servicees from tailscale or cloudflare, I suppose
