Setup a DNS server on a dynamic public ip (lemmy.world)

Hello! I want to set up a pi-hole on my home and connect from my parent's. Both setups have a dynamic IP assigned by my isp and are different networks.

I have a couple of questions:

I can get a domain that updates automatically. But how would I resolve it on the client side?
Is there any way to authenticate on the server? By Mac maybe? That can be spoofed right?

Edit: my bad, thanks for correcting me, Mac is another layer completely

Can setting up a VPN solve both (1) and (2)?
Is there any other way?

Thanks!

I would get a domain name and use ddns to update your rotating IP. Then I would setup wireguard VPN in split tunnel and have your parents network tunnel back to your piholes for dns resolution.

I use cloudflare API for ddns updates but there are plenty of choices for that. If you're using cloudflare for DNS just keep in mind you can't proxy the DNS entry for the ip for your VPN host as CF only forwards traffic over certain ports and they are not configurable (on free plan anyway not sure about paid).

Don't you get a short break in connectivity as the ip changes?

[–] [email protected] 3 points 11 months ago

yes but most isp's (at least where I live) change the IP in the middle of nobody-should-be-awake-anyway o'clock

Plus the connection drops only for a minute or two at most unless ypu set a really high ttl on the domain dns record

You can do DoH over proxied cloudflare I believe

edit: now I'm wondering, is it possible to proxy headscale??
