Windows ipconfig command

The ipconfig command is a Windows utility that displays and manages a computer’s IP (Internet Protocol) configuration. It’s commonly used for troubleshooting network issues and managing network settings.

Basic Usage

The general steps to use ipconfig are as follows:

Open Command Prompt.

Type ipconfig and press Enter.

 

The ipconfig command provides information about the network interfaces on your computer. The output typically includes:

IP Address: The unique address assigned to each network interface on your computer.
Subnet Mask: Defines the network portion of the IP address, used to separate the network from the host portion.
Default Gateway: The IP address of the router or gateway used to access external networks, including the Internet.

ipconfig /all

This flag is used to view detailed IP and network configurations. It displays detailed information about all network interfaces, including:
MAC (Media Access Control) address.
DHCP (Dynamic Host Configuration Protocol) status and lease information.
DNS (Domain Name System) servers.
Connection-specific DNS suffix.

ipconfig /release

Releases the current DHCP configuration for all network interfaces, effectively dropping the assigned IP addresses.

ipconfig /renew

Renews the DHCP configuration for all network interfaces, requesting a new IP address from the DHCP server.

ipconfig /flushdns

This flag is used to clear the DNS cache. It clears the DNS resolver cache, which can help resolve DNS-related issues.

 

This command is a network troubleshooting command. If you’re having trouble with your network connection, ipconfig can help you identify if there are issues with your IP address or connectivity.
DHCP Problems: If you can’t connect to the internet, releasing and renewing your IP address can sometimes resolve DHCP-related issues.
DNS Problems: Flushing the DNS cache can help if you’re encountering issues with resolving domain names.
