A curated field guide that catalogs 49 inventive, often impractical projects that repurpose the Domain Name System for art, tools, tunnelling and protocol play. Entries are grouped into themes - traceroutes that spell lyrics or draw pictures via PTR records, DNS carried over unexpected transports (IRC, SMS, Signal, Twitter, Mastodon, ping, even telephone and a joking “DONUTS” transport), small utilities and toys served from TXT records (blogging via TXT, calculators, weather, Wordle, Wikipedia lookups), and experiments that push DNS toward bulk or stateful uses (HTML-over-DNS, images and MP3 split across records). Screenshots and short descriptions show concrete examples such as traceroutes spelling “American Pie” or a Star Wars story, services like txtrex and dns.toys, and playful servers like CatDNS and Drink.
The collection emphasizes both clever engineering and operational realities: DNS can act as a constrained key-value store, a one‑way browser channel, an IP/VPN tunnel (iodine, SlowDNS), or an encrypted C2 channel (dnscat2), but it faces limits of packet size, caching, timing and security. Entries include practical network‑operator tools (Team Cymru IP→ASN), defensive case studies (malware retrieving payloads from TXT records), and experimental UIs (AI chatbot over DNS). Original content is by Peter Lowe under CC BY 4.0; third‑party items are referenced as examples of DNS’s surprising flexibility and abuse surface.

Writing has traditionally served as proof of work, effort, and understanding within tech companies, often used to demonstrate compliance, effort, or knowledge. However, large language models now challenge this practice by generating plausible content quickly, reducing the value of writing as evidence of genuine work or learning. (seangoedecke.com)
