I used noip.com for like 30 or 60 days. Then I got really annoyed at having to renew the DDNS every 30 days.
After switching to duckdns.org I haven't had any problems whatsoever. It's completely free and you don't have to renew anything manually. You obliviously still need to have a script running to update the DDNS though, otherwise it wouldn't be very dynamic would it.
My mail lived on an Intel atom based mini itx machine for years. I wanted to play with breakup by replication and bought a cheap shell. Now the cheap shell is my only mail server
I have an HP mini PC behind the router, noip.com, no money spent
Same with the HP mini PC. But I have a $12/yr dotcom domain and a script on my server updates the DNS record anytime the IP changes.
My router can update the IP on its own if you configure properly
I recommend cloudflare WARP

Well... electricity.
Yes, of course, but that mini PC uses 15 watts maximum. My main PC uses way more that that
