Agree with the two so far, but to clarify how I use them.
Cloudflare for external/public services. (Like if you run Lemmy). Use the tunnels so random people's traffic aren't hitting your actual IP at all, and it remains proxied through them.
Dynamic DNS if you have an ISP that will change your IP on you randomly. Personally I use namecheap, and they have an API to update when the IP changes. I use pfsense which has a dynamic dns plugin which will update my IP if it changes.
I thought CloudFlare tunnels handled the non-static IP part, so DDNS shouldn't be necessary? I have a tunnel running on an RPi and I THINK it's going to update the IP that CF has if/when my ISP changes it..... I guess I'll find out! 😆
There might be a service in cloudflare that does that - but I'm not aware of it. DNS in cloudflare requires an IP to proxy to, and you would need something (hosted by cloudflare on your rpi theoretically) that then would notify cloudflare that your IP has changed - otherwise cloudflare won't know where it's proxying from.
Cloudflare isn't DNS, it's a proxy that sits in the middle. (Okay it also does DNS, but I mean it's not just routing traffic). Essentiall all cloudflare does is
I'm simplifying a lot but that's the gist. But if your IP changes then cloudflare doesn't know where to get your data.
Right, it's called CloudFlared: https://github.com/cloudflare/cloudflared
