What it does

Router Info reads the network configuration your device has been given by your router and displays it in one clean screen: your gateway address, subnet mask, DHCP lease details, and the DNS servers your traffic is being routed through. It's the fastest way to find your router's local IP if you need to log into its admin panel, verify which DNS server your ISP has assigned, check your subnet size, or confirm that DHCP is working correctly after a network change. No packets are sent to any outside server — the information comes entirely from your device's own network stack. It's free, completely offline, and needs no account or sign-up.

How to use the Router Info

  1. Connect your device to the Wi-Fi network whose router you want to inspect.
  2. Open the Router Info tool. It reads your network configuration immediately — no button to press.
  3. Note the Gateway address — this is the local IP of your router. Enter it in your browser to reach the admin panel.
  4. Check the DNS servers listed. If they show your ISP's addresses and you'd prefer faster or more private DNS, you can change them in your router settings.
  5. Review the subnet mask and DHCP lease time to understand your network's size and how long your IP assignment lasts.

Frequently asked questions

How is this different from just checking my phone's Wi-Fi settings?
Your phone's settings usually show only your own IP and the gateway. Router Info surfaces the full picture: gateway, subnet, DHCP lease start and end, lease duration, and all assigned DNS servers — all in one readable screen.
Does this tool connect to my router directly?
No. It reads the network configuration your operating system has already received from the router via DHCP. It doesn't log into the router or send it any requests.
Why are there two DNS server addresses?
Most routers assign a primary and a secondary DNS server. If the primary fails to respond, your device falls back to the secondary automatically. Common pairs are your ISP's own servers or public resolvers like 8.8.8.8 and 8.8.4.4.
Can I use this information to set a static IP for my device?
Yes. The gateway and subnet shown here are exactly what you need to configure a static IP — just pick any address in the same subnet that isn't already taken, and enter the gateway and DNS values shown.
