There are some free offerings available of dynamic DNS. IIRC DuiaDNS [1] is free. In The Netherlands (a very tiny country though) Xs4all is one of the very few ISPs allowing home users to change the A/AAAA/PTR/MX records of their hostname/IP address (for both their DSL and FTTH offerings). You can get a subdomain or use your own domain, with reverse DNS. They've been doing that since forever. You can also get shell access. They're also a bit more expensive than the competition though. Running your own server has one disadvantage (though it has gotten smaller these days): electricity costs and impact. I'm getting solar and Raspberry Pis and such are pretty marginal though. I suppose you should compare it with AWS and the like? [1] https://www.duiadns.net https://www.duiadns.net
