How do I change my IP address?

The basics

Before reading any of the below information, you need to be aware of some network basics.

1. Know the difference between a static IP addressand a dynamic IP address. See each link for additional information about each of these terms.
2. When on the Internet, it is up to your Internet Service Provider (ISP) to assign and give you your network address seen by the Internet. When on a local network (LAN) or wide area network (WAN) the home or corporate router assigns the IP addresses.
3. If you're planning on designating or using a static IP address, you should be aware of how IP address ranges are handled and be familiar with the netmask. See each of these links for additional information.

Changing your Internet IP address

Modem users

When connecting to the Internet over a dial-up Modem, your ISP will assign your computer a different IP address each time you connect. If you're wanting to change your IP address, try disconnecting and reconnecting. If you're assigned the same address, disconnect for a few minutes and then reconncect.

Broadband users

Broadband service providers will assign your computer or home network a static IPaddress. If you're connected to a broadband network and need to change your IP address try following the steps below.

Disconnect power to broadband modem

Getting a new IP address may be as simple as disconnecting the power to your broadband modem. Disconnect the power from the modem and leave it disconnected for a few minutes. If you have a network router connected to the modem, we also suggest disconnecting the power to the router.

Release the IP address assigned to router

If disconnecting the power to the modem and router did not work it may still be saved in your router configuration. Try releasing and renewing the Internet IP Address for the router. Steps on how to do this can vary depending on the router. However, is often done through the Status or setup in the router setup.

Tip: The Internet IP Address is not the 192.168.xxx.xxx or 10.0.xxxx.xxx address.

• How do I adjust the settings of my home router?

Leave it disconnected over night

If the above two suggestions do not work, disconnect the power to the modem androuter (if applicable) and leave them disconnected overnight or for as long as possible.

Contact the ISP

If none of the above suggestions help you change your IP address, it's possible your ISPprevents a new IP address from being assigned unless it is abandoned for days. In this situation, its usually easiest to contact the ISP to get the IP address changed.

Changing your home network IP address

To change or specify the IP address of your computer for your own local area network (LAN), follow the steps below. Keep in mind that if you're connecting to the Internet with a broadband connection, adjusting your network settings may cause issues with your broadband connection. Finally, if your home network is setup through a network router, that router could be assigning your computer dynamic IP addresses, and specifying a static IP address may cause issues.

Can someone else change my IP address?

Someone who's outside your home network and does not have access to your network router cannot change your IP address. Do not be concerned about your computer's security if your IP address has changed. It's more likely that it's normal behavior than an attack.
