How To Change ip address

 

An Internet Protocol address (IP address) is a numerical way of identifying your computer on a network. Every computer in your home or office has its own unique number that is dynamically generated, but that doesn't mean you can't change the number currently assigned to your machine. If you connect to the Internet with DHCP (Dynamic Host Configuration Protocol), you can change your IP address in a snap.

 

Method in Windows 7

1. Open Network Connections. Click the Start button, then click Control Panel. In the search box, type "adapter," and then, under Network and Sharing Center, click View network connections.

2. Right-click the connection that you want to change. Click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click the Properties button.

• To specify your IP address for IPv4, click Use the following IP address, and then, in the IP address, Subnet mask, and Default gateway boxes, type the IP address settings.
• To specify an IP address for IPv6, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.
• A typical IP address looks like 192.168.0.2; a typical subnet mask would be 255.255.255.0. The Default Gateway is generally the address of your router. For example, the numbers for our system are as follows:
• IP Address: 192.168.0.2 through 192.168.0.12 (for multiple computers)
• Subnet Mask: 255.255.255.0
• DNS: 192.168.0.1

In Windows XP

1. Click on Start in the bottom left hand corner of screen. Then click Run.

• Enter "CMD" and then click OK. You should now be at an MS-DOS prompt screen.
• Type "ipconfig /release" and click "Enter." This will disable your Internet connection. To undo it, type "ipconfig /renew."
• Type "exit" and leave the prompt.

2. Right-click on Network Places or My Network Places on your desktop. Then click on Properties. You should now see a screen titled Local Area Connection, (or something close to that) and all of your other networks (if you have a network hooked up).

Right-click on Local Area Connection and click Properties.

• Double-click Internet Protocol (TCP/IP) from the list under the General tab.
• Click on Use the following IP address under the General tab.
• Create an IP address.
• Press Tab and it should automatically fill in the Subnet Mask section with default numbers (generally 255.255.255.0)
• Click the OK button.
• Click the OK button again. You should now be back to the "Local Area Connection" screen.

3. Right-click back on "Local Area Connection" and go to properties again.

• Go back to the "TCP/IP" settings.
• Select "Obtain an IP address automatically."
• Click the "OK" button.
• Click the "OK" button (when it pops up again). You now have a new IP address.

4. Coda: Most of the time, these steps will work perfectly. But you have to be prepared for some irregularities.

• If you are using a router, for example, you may need to make changes to your router settings before obtaining the new automatic IP change. Otherwise it will automatically reset to the same IP address.
