A programmer had a wild idea:

DNS resolvers cache domain names for days——

What if you could store files in them?

He found 3.9 million open DNS resolvers across the entire internet

Chopped the file into pieces

Scattered them across the web

No hard drive, no database, no cloud

The file lives in the caches of countless servers — servers that have no idea they’re storing anything

The file slowly “dies” as servers one by one forget it

This is one of the most absurd open source projects I’ve ever seen

It’s called dnsfs

What file would you store in a DNS cache?
