Practical Use Cases

Let’s consider a few scenarios where these commands can be particularly useful:

Troubleshooting Internet Connectivity

If you are experiencing internet issues, the first step is to check your IP configuration:

• Use ipconfig to verify your IP address and ensure you are in the correct subnet.
• If the IP address starts with 169.254, it indicates that the computer is not receiving an IP address from the DHCP server. Use ipconfig /release followed by ipconfig /renew to rectify this.

Configuring Static IP Addresses

To configure a static IP address, you might need to either use the graphical interface or the command line:

1. Open the network settings through the Control Panel.
2. Navigate to your network connection properties.
3. Set the IPv4 properties to static and enter your desired IP, subnet mask, and gateway.

Then, use ipconfig /all to verify the settings.
