I use a public VPS and Wireguard. Costs $3.50 for the VPS which has a static IP. I host on my laptop. I can take my laptop anywhere in the world there's an Internet connection and my email and web sites continue to work right from the same VPS IP because my laptop connects to the Wireguard server on my VPS when it comes up.
