docker-cloudflare-ddns VS ddns-updater

https://github.com/oznu/docker-cloudflare-ddns has been archived and perhaps one should avoid it. You will not receive any updates in the future.

That container was last built Mar 21 2020. Looks like this is the source code.

I've seen the cloudflare-ddns solutions on github here and here but it doesn't look like it'd work for my intended use case. Do you know any software that can be selfhosted that allows for that?

Something like CloudFlare ddns docker container will check your external IP every minute or so and automatically update if required

I hate noip. They spam my email and I have to remember to confirm my domain every month or it gets deleted. I just switched to this with cloudflare and its so much better.

Cloudflare DDNS

I've used this in the past: https://hub.docker.com/r/oznu/cloudflare-ddns/

Cloudflare is a nice option.

Setup https://github.com/qdm12/ddns-updater to keep you IP address updated for your Google DNS record. This is only need for inbound access while you are remote so that your DNS record is updated if you IP address changes.

Do you mean something like ddns-updater?

This assumes you have your DynDNS mechanism set up by any means other than the Fritz!Box internals (for example, I use this docker image, in combination with my cloudflare managed domain to achieve DDNS behavior). This means that the Fritz!Box needs to be reachable with the domain you intend to use for your VPN connection. For example, I use vpn...

SOLVED: Thanks to some of the suggestions here I realized the WAN IP wasn't actually changing. The DDNS updater I use: https://github.com/qdm12/ddns-updater uses a bunch of different sources, both http and DNS to determine the current public IP. At lease one of the http sources was no longer working and I have no idea how the DNS sources are supposed to know what my current IP is, that doesn't make sense to me.

I use ddns-updater.

Take a look at qdm12/ddns-updater

Use https://github.com/qdm12/ddns-updater. You can buy a standard domain, and this will keep it pointed at your IP.

if youre public IP isnt static, you will need a dns-updater too.

Use a dynamic DNS service like noip.com. You either use one of their domains like myusername.someDDNScompany.com or you use your own domain. Then you run software like ddns_updater on a raspberry pi or a docker container on your NAS that periodically checks and updates the DNS record with your current home IP.
