With the help of Ben Aaron Goldberg, I solved the SCGI issues so it is
now on a standard port. The new URL prefix is now:

gemini://gemini.bortzmeyer.org/dns

Examples of interesting requests:
 
=> gemini://gemini.bortzmeyer.org/dns/gemini.circumlunar.space IP addresses of the reference site
 
=> gemini://gemini.bortzmeyer.org/dns/cl/NS Name servers of the chilean top-level domain
 
=> gemini://gemini.bortzmeyer.org/dns/protonmail.com/MX Email servers of ProtonMail
 
=> gemini://gemini.bortzmeyer.org/dns/outlook.com/TXT Microsoft loves TXT records
 
=> gemini://gemini.bortzmeyer.org/dns/www.potamochère.fr Of course, it works with IDNs (domain names in Unicode)
 
=> gemini://gemini.bortzmeyer.org/dns/34000.cp.bortzmeyer.fr/LOC Location of cities in France from their zip code (here 34000)

=> gemini://gemini.bortzmeyer.org/dns/76100.cp.bortzmeyer.fr/URI The same, as an OpenStreetMap URI
