Homemade DNS server

[Saearrin]

Is it possible to make a homemade DNS server? The default one from my provider goes down frequently, and Google/Cloudflare's have quite a lot of latency where I live so they are annoying to use. Thought about searching servers with low latency, but don't trust them since they don't have a big company behind it.

Of course it's possible. But know that a homemade DNS server will still need to resolve queries to another DNS if it doesn't know the answer.

Something simple could be Pihole (for ad-blocking) or if you want to completely build DNS from scratch, it's fun on Linux (like Ubuntu Server).

Can you change the dns server your router uses from default?

For kicks, run this DNS benchmark utility from GRC while using your ISP’s default DNS. Post the results.

Yes, using 8.8.4.4 right now.

does it persist if you change it to 1.1.1.1?

Sure you can run one, I've been running one for years. But most likely if you have latency problems to Google/Cloudflare, running your own won't help. It would either have to query the root servers for DNS records, or if you have it set up as a caching forwarder,  forward queries to a provider like Google/Cloudflare or someone else. If you have wider internet problems you'll hit that latency problem with either setup. Having a caching resolver on your network might help you avoid extra lookups, so it's not totally useless, but I'd look into why you have the latency in the first place.
