What is ipconfig?

ipconfig is a built-in Windows command-line tool that displays the current network interface's IP address, subnet mask, default gateway, and more.

Common Parameters

  • ipconfig: Displays basic network information.
  • ipconfig /all: Shows detailed network configuration, including MAC address and DNS servers.
  • ipconfig /release: Releases the current assigned IP address.
  • ipconfig /renew: Requests a new IP address from the DHCP server.
  • ipconfig /flushdns: Clears the local DNS cache.

Troubleshooting

If you experience network connectivity issues or IP conflicts, try running ipconfig /release and ipconfig /renew to obtain a new address, or ipconfig /flushdns to refresh the DNS cache.
