172.16.0.1

172.16.0.1 — Gateway of the Third Private Range

172.16.0.1 is the first usable address of the least known private range. If your network runs on it, that was a deliberate decision.

✦ WHO USES IT

RFC 1918 set aside three private blocks: 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16. The middle one stays popular with companies, VPN concentrators and virtualisation hosts because consumer routers almost never collide with it.

✦ TOOLS INCLUDED

• Network tools: response time, speed and DNS — these tests query public servers on the Internet

• 20 languages, light and dark theme, no account needed

• Factory logins for 298 router brands, with the ones you tried marked

✦ TYPICAL USES

• Open the admin page over the local network

• Measure latency to the gateway

• Read your IP, subnet and gateway at a glance

✦ WORTH KNOWING

A VPN can put 172.16.0.1 into your routing table without it being your WiFi router at all. The app shows the gateway your device is genuinely behind, so you can tell the two apart.

✦ LIMITS

No password is broken and nothing is unlocked from a distance. The app loads the local page of your own equipment and lists factory credentials that are published openly.

Install it, tap once, and get straight to the settings.
