The primary academic work and related technical documentation for this concept include:

DNSFS works by splitting files into small chunks (roughly 180 bytes) and storing them as base64-encoded strings within . Users can "upload" files to open DNS resolvers and retrieve them later using specific hostname queries, effectively treating the DNS cache as a temporary storage medium. IETF RFC 6763 (DNS-SD)

While not solely about DNSFS, this paper provides the most structured and historical analysis of unconventional DNS TXT record usage, including data storage and potential security risks like "leaked" private keys and botnet communication.

The official standard for structuring DNS records (specifically PTR, SRV, and TXT) to facilitate service discovery across networks. Access: IETF RFC 6763 . Key Concept of DNSFS

This research focuses on detecting botnets that use DNS TXT records for command and control (C&C) or data exfiltration, a mechanism very similar to how DNSFS operates. Access: Available via ResearchGate . RFC 6763 (DNS-based Service Discovery)
