Changelog

All notable changes to dnsglobe are documented here. The format is based on Keep a Changelog, and the project adheres to Semantic Versioning.

Unreleased

Changed

  • The resolver table now fits an 80-column terminal without cropping anything that matters: resolver IPs are shown in full, the numeric columns (Ping, TTL, Exp) are right-aligned so their digits line up, units that the header already implies are gone, and where there isn't room for the spelled-out status the verdict moves to a glyph in the left margin (✓ ≠ ! ↻ ∅ ✗) — one place to scan for failures. Wider terminals are unchanged: they keep the status word, the same answer column and the same map/globe thresholds. (#33, #40)
  • The per-row expiry countdown is coarse: at most two digits and a unit (59s, 1m, 59m, 1h, 23h, 1d, 99d). A whole column of seconds ticking out of unison was a distraction, and above a minute the exact second never changed what you'd do. The TTL advisory notes still quote the precise figure (TTL ≈ 2h23m). (#33, #40)
  • Failures now show as a white-on-red badge on the status glyph and word rather than red text, which went washed-out on terminal themes with a mid-toned background (macOS Terminal's "Ocean"). Only the marker is filled — error messages, map dots, the propagation gauge and slow ping times keep the plain red, so the table doesn't turn into a wall of red bars. theme.error accepts the new "<fg> on <bg>" form (for example error = "black on 208"); a plain color still works and means no badge. (#33, #40)
  • Anycast site discovery now asks every resolver for its NSID (RFC 5001) first — a standard EDNS option servers answer with their own node name — and only falls back to the old operator-specific id.server probes when that names no place. More resolvers report where they actually answered from: Lumen shows →JFK, CIRA Canadian Shield →YYZ, DNS4EU →AMS and DNS.SB →KIX where they used to show only the operator's home region. Resolvers you add yourself in the config file can now report a site too, since NSID needs no per-operator support, and Google's site takes one query instead of two. Nothing that already resolved to a site changed. (#36, #39)

Fixed

  • Names with an underscore in the middle of a label are queried instead of failing on every resolver with protocol error: Label contains invalid character. Underscores are legal anywhere in a DNS label — the letter-digit-hyphen rule is about hostnames, not the DNS wire format — so the delegated SPF/DMARC hosts that EasyDMARC, Valimail and friends generate (_spf.514_ax._d.example.com) now resolve like they do in dig. Default and --ecs runs accept exactly the same set of names; previously only --ecs handled these. (#34, #37)
  • A domain that really is malformed (an empty label, a label over 63 characters) is now reported once — as a startup error for a name given on the command line, or in place of the propagation gauge for one typed in the TUI — instead of filling the table with one identical error per resolver, which read like a network outage. (#37)
  • The TTL note no longer lets a single resolver speak for the zone. It used to report the longest TTL any agreeing resolver returned, so one resolver handing back an invented 8423s turned a 300s zone into "TTL ≈ 2h23m" and advised lowering a TTL that was already low. The estimate now ignores reports wildly out of line with the rest of the fleet (never more than a tenth of it), and any resolver that reported one is named on the note line with what it claims — that cache really will serve the old answer after a change, and it is worth knowing which one it is. (#38)

0.4.0 - 2026-07-11

Added

  • Resolvers can be added and removed at runtime: + opens an add-resolver dialog (name and IP, plus optional location and map coordinates, validated like the config file), ↑/↓ highlight a row in the table, and Ctrl+X removes the highlighted resolver. Changes last for the session; permanent resolvers still belong in the config file. A resolver added mid-watch is queried immediately and joins the propagation math. (#30)

  • EDNS Client Subnet (RFC 7871) support: --ecs 203.0.113.0/24 (or ecs = [...] in the config file) attaches that client subnet to every query, so GeoDNS zones answer for that network instead of each resolver's own vantage point. Takes CIDRs or bare IPs, and accepts several subnets to compare how answers converge across client networks: Ctrl+N cycles the active subnet in the TUI (re-querying as it goes), and --once prints one table per subnet plus a convergence summary. Resolvers that deliberately ignore ECS (Cloudflare, Quad9, …) are tagged NO ECS and left out of the propagation percentage — their answer describes their own location, not the probed network. (#14, #29)

  • 3D rotating globe view: the flat resolver map can morph into a spinning orthographic globe, with the resolver status dots riding their continents and hiding on the far hemisphere as the planet turns. The globe keeps the map's braille rendering, adds a faint graticule so the rotation reads even over open ocean, and is tilted 15° so the northern-hemisphere resolver clusters stay clear of the limb. (#26)

  • The view is responsive by default: the square-ish globe needs fewer columns than the 350°-wide flat map, so narrow terminals get the globe (down to widths that previously showed no map at all) and wide ones the flat map — resizing across the threshold animates the morph live. Ctrl+O toggles by hand and pins the choice; --view auto|map|globe or view = "..." in the config file force it outright (flag beats config). (#26)

  • Nix flake support: nix run github:514-labs/dnsglobe builds and runs dnsglobe from source on any system with Nix flakes enabled; specific releases can be pinned via git tag (github:514-labs/dnsglobe/v0.3.0). A devbox.json is included for reproducible development environments. (#10, #21)

  • Custom color themes: a [theme] table in the config file recolors any UI role (accent, agree, differ, error, pending, stale, upstream, muted, coastline, grid) using ANSI color names, 256-color indexes, or hex values. (#27)

Changed

  • ↑/↓ (and PageUp/PageDown) move a highlight through the resolver table instead of scrolling it directly; the view scrolls along to keep the highlight visible. (#30)
  • Tab / Shift-Tab now re-query the checked domain with the newly selected record type right away, instead of waiting for Enter — matching the new Ctrl+N behavior for ECS subnets. (#29)
  • The default palette now stays legible on terminal themes with mid-toned backgrounds, like macOS Terminal's "Ocean": de-emphasized text uses the faint attribute instead of dark gray (dimming your theme's own foreground color, which is always readable), and status colors moved to the bright ANSI range. Past-TTL is now orange to stay distinct from the brighter error red. Set muted = "darkgray" in [theme] to restore the old de-emphasis on terminals that render faint poorly. (#25, #27)

0.3.1 - 2026-07-06

Fixed

  • SERVFAIL answers now count as a propagation signal instead of being discarded as unreachable. A resolver answering SERVFAIL is saying "I tried to resolve this name and could not" — the exact state of a resolver stuck on a delegation whose old nameservers were deleted mid-NS-migration (or a DNSSEC validation failure). Such resolvers now hold the propagation percentage below 100% and keep watch mode polling; they show as ✗ SERVFAIL in the table (FAIL in --once output) with their own footer count. Previously they were lumped in with timeouts/refusals, so a broken delegation could report as fully propagated. (#23)

0.3.0 - 2026-07-06

Added

  • Word and line cursor motions in the domain input: Option/Alt+←/→ (or Ctrl+←/→, or Alt+B/F) moves the cursor by one dot-separated label; Cmd+←/→ (or Home/End, or Ctrl+A/E) jumps to the start/end of the input. Cmd is reported via the kitty keyboard protocol, enabled when the terminal supports it. (#17)
  • Argument parsing via clap: --help and --version now work, invalid arguments get proper error messages, and an optional record-type positional (dnsglobe example.com TXT) sets the starting record type in TUI mode too — previously it was only honored with --once. The long --help also documents $DNSGLOBE_CONFIG and the config-file syntax.
  • Anycast site geolocation: large anycast resolvers (Quad9, Cloudflare, Google, OpenDNS, CleanBrowsing, Neustar UltraDNS) are asked which POP is answering via identification queries (id.server CH TXT and operator-specific probes). The discovered site shows in the Loc column (e.g. →YUL) and the resolver's map dot moves to the POP actually serving you. (#13)
  • Cache-expiry countdowns: a live Exp column next to the static TTL shows when each resolver's cache entry must be refetched; the propagation gauge shows the fleet-wide bound ("old answers expire in ≤ X"). Watch mode skips re-polling resolvers that agree with the majority until their TTL runs out. (#12)
  • TTL advisory: once a round settles with full agreement and the zone's TTL is ≥ 1 hour, a footer hint suggests lowering the TTL before a planned record change. (#12)
  • Stale-cache verdicts in watch mode: ! PAST TTL flags a resolver serving an answer past its own reported TTL, ↻ UPSTREAM flags one that refetched and still got old data back (e.g. a lagging secondary authoritative server). Both surface in the status column and on the map. (#12)
  • TOML config file for custom resolvers: add to (or replace) the built-in list via ~/.config/dnsglobe/config.toml (XDG-aware, DNSGLOBE_CONFIG override). Entries take a name and IPv4/IPv6 address, plus optional location and lat/lon for the world map; invalid config is rejected at startup with the offending entry named. (#11)
  • CI workflow running cargo fmt, clippy, and tests on PRs and main. (#11)
  • README: Arch Linux AUR package information. (#8)

Changed

  • Releases are now cut by merging a version-bump PR: the release workflow is dispatched automatically and publishes to crates.io (new) as well as Homebrew, so cargo install dnsglobe stays current with each release. (#19)

0.2.0 - 2026-07-05

Added

  • Table sorting: Ctrl+S cycles sort order across resolver / location / time / status / answer; sorts are stable, so sorting by location doubles as group-by-location. (#4)
  • README demo GIF (recorded with vhs) and crates.io badge. (#3)

Changed

  • Rust edition 2021 → 2024 (rust-version 1.85) and dependencies updated to latest: ratatui 0.30, crossterm 0.29, hickory-resolver 0.26. (#4)

Fixed

  • Error-message truncation panicked on multi-byte UTF-8 characters straddling the cut point; truncation now backs off to a char boundary. (#4)

0.1.1 - 2026-07-04

Added

  • Release pipeline via dist (cargo-dist): every v* tag builds prebuilt binaries for macOS (arm64/x64), Linux (arm64/x64), and Windows, attaches them to the GitHub release, and publishes a Homebrew formula to 514-labs/homebrew-tap. First release with prebuilt binaries. (#1)

0.1.0 - 2026-07-04

Initial release.

Added

  • Global DNS propagation checker TUI: queries 34 verified public resolvers worldwide in parallel and compares their answers to show how far a record has propagated, in a scrollable table with per-resolver latency, TTL, status, and answers.
  • World map with per-resolver status dots, colored by whether the answer agrees with the majority.
  • Answer-overlap grouping, so round-robin pools count as one answer; refused/unreachable resolvers are excluded from the propagation percentage.
  • Record-type selector (A, AAAA, CNAME, MX, NS, TXT, SOA) and watch mode that re-polls every 30s until all responding resolvers agree.
  • --once plain-text mode for scripts.
