Using DNS TXT records as a distributed storage

Contrary to the popular belief, TXT records are not limited to a 255 chars string, but can be composed of multiple 255 chars strings!

Here’s an example page hosted on this site. The first HTML page fetched will do a DNS resolution to dns-page.syscall.cafe, fetch the TXT record, and replace the whole page with the content of the record. You can also do it by hand by running:

dig +short TXT dns-page.syscall.cafe | sed 's/[\" ]//g' | base64 -d > index.html 

Due to DNS records being replicated across the globe, this allows free, distributed and fast access to the data. Thanks DNS!
