There’s a writeup out there where you can use the GoDaddy API to update your actual DNS IP every time your external IP changes. Not free, but works pretty well.
Buy a domain from Cloudflare and use your firewall (pfSense, OPNsense, etc) to do the dynamic DNS updates for you.
Similar to what I do. I just have a script that triggers on IP change directly on my router.
No need to buy the domain from cf, you can just set nameservers
True, but there are no extra costs added to domains on Cloudflare
Hmm, you’re actually right
But I would like to add that namecheap has coupons for the first year. So you can register a new cheap domain every year
So also it’s probably a good idea to register it from nc and then transfer to cloudflare
edit: lol, i’m even transferring some of my domains to cf right now (although cf is not the company I wish to trust, but namecheap is not one of them too)
For a simple dynamic DNS, I have been using https://www.duckdns.org/ for a few years and been happy so far

I dunno if you’re into scripting, but what I do is check my IP, and then update it via the API that Dreamhost (who are the nameservers I use) provide. If your nameservers have a public-facing API, that might be an option.
I recommend deSEC.io, it’s free. They offer both full DNS hosting (so you can update the A/AAAA records for one of your own domains through their API) and dynamic DNS with subdomains under
.dedyn.io. Both variants are widely supported, for example OpenWRT and ddclient include support out of the box.If you choose to use them for DNS hosting I should mention that deSEC is a German service with a mission similar to Let’s Encrypt, only for DNS: they’ll host anybody’s DNS for free on one condition, that they enable DNSSEC. They generate and maintain it for you, you just have to enable it at your registrar (which amounts to copy-pasting the keys). (If you just use .dedyn.io for DDNS you don’t have to worry about this.)
Thanks for mentioning desec.io! I’ve read about it in c’t a few years ago, but didn’t find it a few months ago.
