A Gemini-to-DNS gateway

Just add a domain name to `gemini://gemini.bortzmeyer.org/dns/` and you'll get the answer as a nice gemtext. Most of the time, the answers are links that you can follow (name-to-address, address-to-name, etc). You can also add the type (MX, NS, LOC, etc) after the domain name and a slash.
