The DNS Museum collects 49 of the strangest things people have done with DNS

A reference catalog of 49 exhibits showing DNS pushed far beyond name resolution: traceroutes that spell out "American Pie" lyrics through PTR records, DNS over SMS, Telegram, Signal, and even a phone call, plus DNS-based blogging, a text adventure, a calculator, and an AI chatbot. Tunnelling projects like iodine and dnscat2 sit alongside playful servers such as CatDNS and dns.toys, all documented as inventive and deliberately impractical.
