GoKawiilDeveloper showcase catalogs unconventional uses of DNS for data, audio, file transfer and tunneling
A roundup documents a wide range of experimental projects that repurpose the Domain Name System beyond simple name resolution, including tools like NUM, DNSFS, DNSKV, CatDNS, iodine and SlowDNS. These projects use DNS records and lookups to stream audio, store key-value data, transfer files, run VPNs, and even power a chatbot, alongside a note that DNS TXT records can also serve as a channel for malware payload delivery.
