dnsglobe
A global DNS propagation checker for your terminal — a Rust TUI that<br>queries 34 public DNS resolvers around the world in parallel, compares their<br>answers, and shows the propagation of your record on a world map.
Think dnschecker.org / whatsmydns.net, but in your terminal, with watch mode:<br>start a check and it re-polls until the record has propagated everywhere.
Resolvers span the global anycast networks (Google, Cloudflare, Quad9),<br>North America, Europe, Russia, the Middle East, East Asia, and the southern<br>hemisphere (Telstra AU, SafeSurfer NZ, UOL BR) — each queried directly, so<br>you see every server's own current view of the record.
Each resolver is queried directly (no cache, EDNS0, TCP fallback for<br>truncated answers), so what you see is each server's own current view of the<br>record. Answers sharing any record are grouped together — so round-robin DNS<br>(each resolver caching a different subset of an IP pool) counts as one<br>consistent answer, not twenty conflicting ones. The propagation gauge shows<br>how many resolvers are in the majority group; outliers are flagged<br>≠ DIFFERS once all results are in.
On terminals ≥150 columns wide, a world map appears on the right with one<br>dot per resolver, colored by status (green agrees, magenta differs, red<br>error, yellow in flight).
Usage
Install:
brew install 514-labs/tap/dnsglobe # Homebrew (macOS/Linux)<br>cargo install dnsglobe # from crates.io<br># or grab a prebuilt binary from the GitHub Releases page
Run:
dnsglobe # start empty, type a domain<br>dnsglobe example.com # query immediately and watch<br>dnsglobe --once example.com TXT # no TUI: print results, exit (for scripts)
Keys
Key<br>Action
type / ⌫ / Del<br>edit domain
←/→ / Home/End<br>move cursor in the domain field
Enter<br>start the check and watch: re-polls every 30 s until propagation reaches 100%
Ctrl+R<br>stop or resume watching
Tab / Shift-Tab<br>select record type (A, AAAA, CNAME, MX, NS, TXT, SOA)
↑/↓ / PgUp/PgDn<br>scroll the resolver table
Ctrl+U<br>clear domain
Esc / Ctrl+C<br>quit
Notes
Several resolvers are anycast networks, so the responding node is the one<br>nearest to you; the location column is the operator's home region.
Resolver list lives in src/resolvers.rs — add or remove entries freely.<br>Every entry was verified to answer external queries; many well-known ISP<br>resolvers (and, notably, all major African ones) refuse queries from<br>outside their network, so they can't be included.
