Changelog

What's changed on netsh.io, newest first.

LatestVersion 1.32Sep 24, 2026

DNS Trace, TLS Configuration, credit-weighted APIs, and higher limits

  • New DNS Trace tool follows a lookup from the root servers through the TLD to the authoritative nameserver, with a REST endpoint.
  • The DNS Resolution guide is now a full reference: root servers, caching and TTLs, a real trace walkthrough, glue, CNAMEs, DNSSEC, and a troubleshooting playbook.
  • New TLS Configuration tool checks supported protocols, cipher, ALPN, SNI, certificate trust, and handshake timing, with a REST endpoint.
  • Reverse DNS Lookup and a lightweight My IP endpoint (your public IP as seen by NetSH) are now available through the REST API.
  • API requests now use credits: simple lookups cost 1, heavier diagnostics cost more, and each endpoint's cost is shown in the API docs.
  • Each account can now hold up to 3 active API keys.
  • Web tool rate limits raised: every tool now allows at least one more request per minute.
  • MTR and Traceroute show a moving progress bar while they run.
  • HTTP Headers results now fit phones and tablets.
  • Website Health is more accurate: failures name their real cause, redirect-only domains with certificate mismatches still show their redirects, and non-web hosts such as mail servers read "Likely not a web server".
  • Upgrade button on the account page, a limit notice when you reach 3 API keys, and better spacing throughout the dashboard.
Version 1.31Sep 21, 2026

Instant guides search, refreshed guide cards, and refined diagnostic tool links

  • The Guides Hub (/learn) now features an instant search with curated popular queries instead of a static card grid.
  • Search results now display companion diagnostic tool links with their native icons and names.
  • Interactive Diagnostic Tools sidebar now features three randomized utilities in an elegant, borderless tile layout.
  • Homepage featured guide cards redesigned with a lighter, minimalist layout and subtle category indicators.
  • Fixed layout overflow and eliminated horizontal scrollbars across all viewports on the Guides Hub.
Version 1.30Sep 15, 2026

Rebuilt homepage command bar, a fairer rate limit, and account fixes

  • The homepage's "Run" button now rotates through top tools while you type nothing, freezing the instant you type or open its dropdown; the old quick-link pills are gone.
  • Fixed the homepage's tool picker offering tools that couldn't actually accept what you'd typed (a URL, IP, or domain).
  • The homepage's live API example now rotates through Ping, DNS Lookup, SSL Certificate Checker, and WHOIS instead of always showing the same one.
  • Removed the "Get started for free" hero link and the API section's old single-example layout in favor of a two-column API pitch with a live terminal example.
  • API Documentation's sidebar is now larger on desktop, and a simple search bar on mobile instead of the full category list; every reference page now links to a related endpoint at the bottom.
  • API docs navigation now offers Print instead of Download PDF, and printing from the API reference page happens automatically.
  • Fixed the account icon staying visible after sign-out until a manual refresh, and sign-out now stays on the current page instead of redirecting away.
  • Fixed signing in with Google when you'd previously signed up with the same email via a magic link.
  • Free API tier raised from 100 to 300 requests/day.
  • Rate limits are now weighted by how expensive each tool actually is to run, split between a per-person and a shared-network allowance, with a live countdown shown when you hit one instead of a static error.
  • Fixed Port Checker being throttled far more aggressively than every other lightweight tool.
  • Fixed the site's Content-Security-Policy silently blocking analytics.
Version 1.29Sep 9, 2026

MTR, a redesigned Speed Test gauge, and search-visitor sidebar collapse

  • Added MTR: a live table combining Ping and Traceroute, showing loss and latency at every hop along the path.
  • Speed Test's gauge is bigger, shows live Kbps/Mbps/Gbps units while running, and the live card now has a top progress bar.
  • Speed Test's server info row is now a full-width band, consistent between the running and results screens, with the copy button moved inline.
  • Added an MTR guide with a step-by-step diagram; the Ping guide (now "Ping and Network Latency") got the same diagram plus three new FAQs.
  • Added a Kbps/Mbps/Gbps explainer with real-world examples to the Speed Test guide.
  • The sidebar now starts collapsed for visitors arriving from a Google, Bing, or DuckDuckGo search result.
  • Fixed a DNS Lookup breadcrumb/structured-data mismatch, and added FAQ rich results to the Ping and DNS Propagation guides.
Version 1.28Sep 8, 2026

Live-checking Is My Site Down, dedicated pages for 28 popular sites, and a WHOIS accuracy fix

  • Is My Site Down now checks live — DNS, Connect, TLS, and HTTP each resolve in sequence instead of one instant result.
  • Redirect chains are now collapsible, and status codes link to the HTTP Status Codes guide with a plain-language reason.
  • Added a note for results blocked by a site's own bot protection (e.g. Cloudflare) — still reachable, just not what a visitor sees.
  • Added dedicated, always-live pages for 28 popular sites — "Is Google Down?", "Is ChatGPT Down?", and more.
  • Fixed two WHOIS bugs that could wrongly show a registered domain as "not registered" (.io domains, and premium-release domains).

  • Those seven tools now show "Learn More" and "FAQ" links, same as every other tool.

Mail Health Check, and live-streaming fixes

  • Fixed a Traceroute bug where multi-IP hosts (Cloudflare, GitHub, and similar) could wrongly show as "not reached."
  • Traceroute output now adds a blank line before the summary.

  • Expanded About, Contact, and Terms with more complete content.
Version 1.25Sep 2, 2026

Two new tools, and a reorganized sidebar

  • Added Traceroute — hop-by-hop path with round-trip time and reverse DNS at each router.
  • Added MX Lookup as its own tool — priority, resolved IP, and mail provider, no longer folded into DNS Lookup.
  • The sidebar is now grouped into four collapsible categories, ordered by actual usage.
  • Ping now suggests a relevant next check based on the result, not one fixed suggestion.

Reliability fixes and a link preview image
