DNSGlobe – Rust TUI to watch DNS propagate around the world

dnsglobe

A global DNS propagation checker for your terminal — a Rust TUI that queries 34 public DNS resolvers around the world in parallel, compares their answers, and shows the propagation of your record on a world map.

Think dnschecker.org / whatsmydns.net, but in your terminal, with watch mode: start a check and it re-polls until the record has propagated everywhere.

Resolvers span the global anycast networks (Google, Cloudflare, Quad9), North America, Europe, Russia, the Middle East, East Asia, and the southern hemisphere (Telstra AU, SafeSurfer NZ, UOL BR) — each queried directly, so you see every server's own current view of the record.

Each resolver is queried directly (no cache, EDNS0, TCP fallback for truncated answers), so what you see is each server's own current view of the record. Answers sharing any record are grouped together — so round-robin DNS (each resolver caching a different subset of an IP pool) counts as one consistent answer, not twenty conflicting ones. The propagation gauge shows how many resolvers are in the majority group; outliers are flagged ≠ DIFFERS once all results are in.

On terminals ≥150 columns wide, a world map appears on the right with one dot per resolver, colored by status (green agrees, magenta differs, red error, yellow in flight).
