Netlink: IP Monitor & VPN Test
Know when your exit IP changes
Only for Mac
Free · In‑App Purchases
Mac
Is your VPN covering everything? Netlink watches your Mac's exit IP and tells you the moment it changes -- a new address, a new country, or traffic that slipped outside your VPN.
WHAT NETLINK CATCHES
• Exit IP changes: while Netlink is in your menu bar, it checks your exit IP in the background (every 1 to 30 minutes) and notifies you when it changes
• IPv6 traffic that may bypass your VPN tunnel
• Split routing: the two lookup routes see different exits, or some sites see a different exit IP than your main one
• VPN, data-center and Tor flags, matched against lists built into the app -- your IP is not sent to any reputation service, and a miss does not prove an IP is clean
• A system time zone that doesn't match your exit
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
• 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 for most tools. 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.
• Keep watch: alerts when your exit country, ISP or DNS servers change, when the two lookup routes disagree, or when your score drops; an optional recheck of AI services after an exit change (off by default); certificate expiry monitoring
• Full results: AI service check, multi-location probing, speed test, 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
• More: path trace, speed test history, Markdown / JSON / CSV export and share cards (free: watermarked PDF and score-gain image), longer history, and optional iCloud sync between your Macs through your own private iCloud database, encrypted on the device so the developer can't read it (off by default)
MENU BAR, WIDGETS & EXTENSIONS
• Menu bar: a live color-coded score; click it for the Status Panel with Inspect Now.
• Desktop widgets: "Netlink Status" (free) with an Inspect button and "Netlink Dashboard" (Pro) with the score trend. Widgets show no IP address and never go online.
• Control Center (macOS 26 and later): the "Netlink Inspection" control starts an inspection in one tap.
• Floating widget: an always-on-top capsule with exit IP and score; Pro adds more styles.
• Shortcuts, Share menu and Services menu: read the latest result, start an inspection, or send a domain to Domain Diagnosis; nothing starts by itself.
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.
Netlink checks your own connection; it is not a VPN service. Some results depend on public services and may vary by region, carrier or firewall. Results are for reference and are not a guarantee of security, anonymity or compliance.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- The Pro comparison now leads with “Exit change alerts & AI auto-recheck” (AI recheck is optional and off by default); the “Alerts & profiles” section moves up
- Refreshed the bundled offline IP lists (VPN, data center and Tor)
