ddns-updater VS desec-stack

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.

NB. I do not know the number of POP for deSEC but it is certainly more than 1.

https://desec.io/

https://www.securesystems.de/dns-security/

Try deSEC.io instead, its also free, run by a non-profit, no ads, no premium accounts, based in germany. They offer subdomains in the form of example.dedyn.io but you can also set your domains nameservers to theirs and manage your own domain DNS through their controlpanel.

https://desec.io is excellent.

Although not selfhosted maybe https://desec.io/ ?

If you discover malicious content, please let us know at support AT desec.io and we'll do our best to investigate and, if terms are violated, remove DNS service for that domain (see §5 of our terms, https://desec.io/terms).

Less cloudflare? You can simply use a different provider to manage your domains and transfer over for free. https://desec.io is excellent and can be used with any domains and with lets encrypt wildcard certs.

https://desec.io/ probably?

There are "dyndns" services, which give you a (sub)domain name you can assign to your dynamic IP, e.g.: https://desec.io/
