I host personal and semi-commerical websites/apps from home on a 500/500 fiber connection. The hardware is an older HP G1 800 SFF, which you can buy refurbished for ~€150, much more bang for your bucks than a Pi. Proxmox makes it possible to host many webservers and services on LXC containers. But of course, a Pi would work too :) I have choosen to treat IPv6 as the default stack as I can point directly to the address from outside without any NAT. A reverse proxy handles all "legacy" IPv4 requests. My IPs do change once in a while, but I have made a little bash script that updates the DNS via my domain registrars API, works like a charm!
