DNSCDN

A Golang CLI for storing files on the great Domain Name System. Who doesn't need one more reason to debug DNS?

Overview

I started wondering what limits are on DNS records, in terms of content size, which led me down the road of wondering if it would be terribly difficult to store data in chunks across a variety of records.

As it happens it's rather trivial. More about this project can be read on my blog
