Cloudflare has everything you could need to simplify dynamic DNS. The free plans actually cover most of my personal usage and of course paid version for anything else.
The selection of TLDs Cloudflare supports is weird. I checked them out earlier, and they list .dev as “coming soon” even though it was made publicly available in 2019. This makes Cloudflare a non-option for me as I have a handful of .dev domains I would need to transfer somewhere.
Oh. That sucks. I had a few non supported TLDs a few years ago and was happy to find them supported recently. I moved everything from Google to cloudflare last year. Maybe you can ping them @[email protected] on lemmy to check if they have an ETA for .dev. I just asked them that same question so will update you if they answer.
Namecheap is pretty good for that. They also have ANAME support. They're one of the more expensive registrars, but good to use for 1 domain with all of your dynamic stuff.
