How to Release an IP Address in Windows Vista

Releasing and renewing your IP address can help you troubleshoot connection issues.

An IP address acts as an identification number for your computer when you are connected to the Internet. Some service providers give users dynamic IP addresses that change periodically. If you release your current IP address, you may receive a new IP address when you renew your address. If you want to attempt to change your IP address or if you have problems connecting to the Internet, you can release and renew your IP address.

Instructions

1. Click the "Start" button, and then click "All Programs" followed by "Accessories." Right-click "Command Prompt" and click "Run As Administrator." Type your administrator password or click "Continue" if prompted.

2. Type "ipconfig /release" (without the quotes) at the prompt, and then press "Enter" to release your IP address.

3. Type "ipconfig /renew" (without the quotes) and press "Enter" to obtain a new IP address.

Tips & Warnings

• If you have a static IP address, releasing and renewing will not change your IP address.
