Netlink — Network Check

IP, DNS & proxy check

Only for Mac

Free · In‑App Purchases

Mac

Netlink shows your Mac's network environment in one click -- exit IP, DNS, IPv6, VPN / Tor flags and time zone consistency, summarized into a single score. ONE-CLICK INSPECTION Diagnostics runs eight stages in about 1.5 to 2 minutes, and you can stop after any of the first six. It adds up to a score with a five-tier grade, drawn as an exit path map. Issue cards group fixes by root cause and open the right System Settings pane. Compare any two inspections to see what changed. WHAT YOU CAN CHECK • Public IP: exit IP read through two lookup routes and cross-checked; country, ISP and VPN / data-center flags from data built into the app; city-level location on macOS 26 and later • IP Reputation: VPN / hosting and Tor exit flags, matched against lists built into the app; a miss does not prove an IP is clean • Local Network: interfaces, gateway, DNS servers, system proxy and IPv6 • System: system vs exit time zone, plus system and hardware overviews • Reachability: whether built-in services and your own sites respond, and how fast • History: exit-IP timeline, score trend and event timeline TOOLS DNS records, TCP ping, port check, HTTP headers and redirects, ASN and registration info, global DNS / HTTP, proxy PAC test, outage check, IPv6 dual stack and an exit and config self-check. Daily-run tools show their conclusion free once a day; Pro shows full results, unlimited (exit and config self-check and certificate check: full results daily). The hosts viewer and five utilities -- CIDR, QR code, URL / Punycode, timestamp, MAC address -- are free and run only on your Mac. NETLINK PRO A one-time purchase, no subscription. AI service check, multi-location probing, speed test (built into macOS), domain diagnosis, connection timing and direct-vs-proxy comparison run free once a day with their conclusion; Pro unlocks full details and removes the limits. Pro also adds path trace, speed test history, certificate expiry monitoring, rule alerts, Markdown / JSON / CSV export and share cards (free: watermarked PDF only), longer history and optional iCloud sync. MENU BAR, WIDGETS & EXTENSIONS • Menu bar: a live color-coded score; click it for the Status Panel with Inspect Now. • Desktop widgets: "Netlink Status" (small, medium; free) with an Inspect button, and "Netlink Dashboard" (medium, large; Pro) with the score trend. Add them via Edit Widgets. Widgets show no IP address and never go online. • Floating widget: an always-on-top capsule with exit IP and score (Settings › Menu Bar); Pro adds card, dot and strip styles and an animated character. • Shortcuts: four free actions -- read the latest result, start an inspection, open a page, diagnose a domain. • Share menu and Services menu: select a domain and choose "Netlink" in the Share menu, or Services › "Diagnose Domain with Netlink", to fill it into Domain Diagnosis; nothing starts by itself. If it is missing from the Share menu, turn it on in System Settings › General › Login Items & Extensions › Extensions › Sharing (macOS 14: Privacy & Security › Extensions › Sharing). ICLOUD SYNC (PRO, OFF BY DEFAULT) Sync score history, IP history and environment profiles between your Macs through your own private iCloud database, encrypted on the device so the developer can't read them. PRIVATE BY DESIGN No accounts, no ads, no tracking, no analytics. Netlink runs sandboxed with outbound-only networking. Before going online it lists what each provider receives; without your agreement it works with local information only. Results stay on your Mac unless you turn on iCloud sync, and one click clears them. NINE LANGUAGES English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, French, Spanish and Portuguese -- switch instantly in Settings. Some results depend on public network services and may vary by region, carrier or firewall. Results are for reference and are not a guarantee of security, anonymity or compliance.

- Free and Pro adjusted: daily-run tools show their conclusion free once a day, Pro shows full results, unlimited (exit and config self-check, certificate check: full results daily). Free export is the watermarked PDF only; 3 free comparisons - New Tools page for everyday network tools: DNS record lookup, TCP ping, port check, HTTP headers & redirect chain, ASN & registration info, global DNS / HTTP, proxy PAC test, certificate check. The hosts file viewer and five utilities (CIDR, QR code, URL / Punycode, timestamp, MAC address) are free, unlimited and local only - New Outage check: when a site won't open, it tells if your Mac, link or the server is to blame. - New in Pro: path trace (mtr) with per-hop ASN, loss and latency; speed test history with a bandwidth trend; certificate expiry monitoring for up to 20 domains, checked daily, reminders at 30 / 14 / 7 days - New IPv6 dual stack compares your IPv4 and IPv6 exits without affecting the score; the exit and configuration self-check reviews proxy, DNS and IPv6 setup and compares UDP and HTTP exits - Score details gain issue cards: deductions grouped by cause, fixable ones show "about +N (confirm by re-testing)" linking to System Settings; a captive portal prompts you to sign in, then re-tests automatically - Compare two inspections: see what changed in score and network - Scoring: the five grades now break at 80 / 65 / 50 / 35; an exit in a service-restricted region is information only, with no deduction; the default low-score alert threshold is 50 (only if you never saved alert settings). After updating, the home page shows "No inspection yet" until you re-inspect - Desktop widgets: small and medium widgets get an Inspect button (free); new Pro widget "Netlink Dashboard" (medium / large) with the score trend and change since last time, plus optional exit, gateway latency and latest event - Floating widget: new Card, Dot and Strip styles and an animated character (Pro, previewable before buying; Capsule stays free). Renamable; animation Lively, Minimal or Off, paused when covered, on display sleep or in Low Power Mode; draggable, configurable click action and content; hidden under full-screen apps - System integration: Shortcuts gets four actions -- read the latest result, start an inspection, open a page, diagnose a domain (free). With text selected, Services › "Diagnose Domain with Netlink" or Share › "Netlink" hands a domain over. They only fill in Domain Diagnosis, never start it; it counts toward the daily free run, and the share extension never goes online - Errors show a short code; Send Feedback can attach diagnostics (no IP) and an optional window screenshot, after confirmation - New optional iCloud sync in Pro (off by default): score history, IP history and environment profiles sync between your Macs via your private iCloud database, encrypted on the device and unreadable to the developer; Clear Inspection Traces can delete them from iCloud too - More: new app and menu bar icons; the window fits 13-inch screens; first launch (also after updating) lists what each service receives online and asks for consent; declining keeps local features, and you can withdraw in Settings anytime; auto refresh after a network change is rate-limited; decorative animations pause in the background; sidebar: Inspection, Connectivity, Health are now Diagnostics, Reachability, History; AI service check concludes after three rounds; reachability and speed tests can be stopped, keeping the last result - IP country, operator, VPN / data-center and Tor exit lists now ship inside the app, so the risk score and open-proxy check are gone and no key is needed; the speed test uses macOS's built-in one; ISP names come from a new source, so re-add older Known Networks entries if needed; from macOS 26, the system downloads city-level location in the background; with no list match, IP Reputation shows an unscored IP profile (network type, operator / ASN, exit location, exit consistency)
