I don't even bother with playit.gg - just forward a couple ports on the router and pass out my ip. Only time my dynamic ip changes is when I lose power, and if I've lost power the server is down for "Maintenance" anyways.
Or you can just use a dynamic ip service and use that URL anyway. That would keep the IP up to date. That is what I have done for years and it has worked well.
