ipconfig Guide for Windows

Find your router IP address easily.

Quick network diagnostics with ipconfig.

What is ipconfig?

ipconfig is a built-in Windows command-line utility that displays current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. It's essential for troubleshooting network issues and finding router IP addresses on devices running Windows 10, 11, or earlier versions.

How to Find Your Router's IP Address on Windows Using ipconfig

The router's IP (default gateway) is the address used to access its admin panel for configuration. Common defaults: 192.168.1.1 (Netgear/Linksys) or 192.168.0.1 (TP-Link). Here's how to find it precisely via Windows:

  1. Open Command Prompt: Press Windows key + R, type "cmd", and press Enter. Alternatively, search for "Command Prompt" in the Start menu and open it. For admin privileges (if needed), right-click and select "Run as administrator".
  2. Execute ipconfig: Type ipconfig and hit Enter.
  3. Find the Active Adapter: Scroll to your connected Ethernet or Wi-Fi adapter section.
  4. Locate the Default Gateway: Look for "Default Gateway . . . . . . . . : xxx.xxx.xxx.xxx". This is your router's IP. For example, 192.168.1.1.
  5. Use ipconfig /all for Confirmation: If needed, run ipconfig /all to see more details, including the DHCP Server (often the same as gateway).
  6. Test Access: Open a browser and enter the gateway IP (e.g., http://192.168.1.1). It should prompt for router login (defaults like admin/password - change for security).
  7. Troubleshooting:
    • No Gateway Listed: Ensure connection; run ipconfig /renew to refresh DHCP lease.
    • Multiple Gateways: If dual-band Wi-Fi or multiple networks, connect to the primary one.
    • For Modems/Routers: If using a combo device (e.g., from Comcast/Xfinity in the US), the gateway might be 10.0.0.1.
    • IPv6: Focus on IPv4; IPv6 Default Gateway is under "IPv6 Address" but less common for admin access.

Example Output Snippet:
Default Gateway . . . . . . . . : 192.168.1.1

Troubleshooting ipconfig Issues

  • Command Not Recognized: Ensure you're in Command Prompt, not PowerShell (use ipconfig there too, but cmd is simpler).
  • No IP Shown: Check network connection; disable/re-enable adapter in Settings > Network & Internet > Change adapter options.
  • APIPA Address (169.254.x.x): Router DHCP issue - restart router, or set static IP temporarily.
  • Multiple IPs: Use the one for your main connection; ignore loopback (127.0.0.1) or virtual adapters.
  • Windows Version Differences: Works on Windows 7+, but on older systems, use winipcfg (rare now).
  • Advanced Commands: ipconfig /flushdns to clear DNS cache if resolving issues; ipconfig /release then /renew for fresh IP.
