Ubuntu has systemd-resolved listening on port 53 by default. In case you want to run your own DNS server, you can't because port 53 is already in use, so you'll get an error similar to this: "listen tcp 0.0.0.0:53: bind: address already in use". This article explains how to stop systemd-resolved from using port 53 on Ubuntu.

Stop Telling Users Their DNS Is Wrong
If you’re like me, you’ve had the experience where you add a DNS record for a service. You triple check it. The app still says it’s invalid. You wait. You check again. Still invalid. You start wondering if you did something wrong. You didn’t. The app is just checking DNS the wrong way. If you’re building a product that asks users to add DNS records, please take the time to verify DNS records in the correct way.

Nace XDP DNS, un servicio público de resolución blindado contra los bloqueos indiscriminados de direcciones IP
bandaancha.euI've been pondering about having the browser resolve at:// URLs. I have been thinking that we could introduce a DNS-like (maybe DNS itself?) entity that goes from did:plc to URLs, the same way DNS goes from names to IP, and have the browser depend on that similar to how it depends on a DNS server.
agree i'm doing this (handle is my personal site) but i want to take it further - i want my site content served directly from my pds without needing a third party host not sure there's a path to get there yet.. DNS needs to understand at:// or maybe the PLC could mediate somehow?
