How to Change Your IP Address

There are many methods to change your IP address. Some methods will work for you but may not work for someone else and vice versa. To clarify, we're going to cover how to change your IP address in Windows 10, 2000, XP, 2003, and Vista using command prompt.

What If I Have a Static IP Address?

Depending on your Internet Service Provider (ISP) your IP assigned can be a dynamic IP address or static IP address.  If your IP address is static, then you can't change it without contacting your ISP.

However, although not impossible, it is very rare that an ISP would assign you a static IP without some sort of increased level of service like a business account. Furthermore, an ISP can set a lengthy lease time for your IP address and make it look like you've been assigned a static IP.

For instance, if you have a long lease time (explained in this article), then you may not be able to change your IP address without leaving your modem or Wi Fi router unplugged for a long period of time (more than 8 hours), or without cloning your MAC, which is explained later in this article.

That is to say, it definitely helps if you know how the IP is being assigned to you.

In conclusion, you can read our article What Is DHCP – Overview of IP Address Assignment to get a better understanding.

What Is An IP Address Lease Time?

An IP lease time is the amount of time your ISP determines you’ll be assigned a particular IP address.   However, some IP lease times could be just a couple of hours, where some are set to a few days, and other IP lease times could be set for as long as a year or more. To clarify, this setting is completely up to your ISP internet service.

For instance, one of the easier methods to change your IP address is to turn off your modem/router/computer overnight. To clarify, this method will not work if your ISP has a long lease time set for your IP.

In conclusion, the following method will only work if your computer is being assigned your external IP and not a Wi Fi router.  You can check out the article External IP Address Assigning to Computer for further clarification.

If your connection is direct to your computer and your computer gets the public IP and not a Wi Fi router, you can try the following steps to change your IP address:

Manually Assigning IP Address to Change Your IP Address

Some people have inquired how to manually change your IP address. This is possible, but you run a risk of your ISP banning you from connecting to the internet. For instance, to manually change your IP, follow the steps above for your Operating System.  To clarify, in step 9 or 10, depending on your O/S, enter an IP similar to the one displayed in the command prompt window.

For example, if the IP displayed in the command prompt window is 75.1.2.3, change yours to 75.1.2.4. You’ll also need to manually enter the Subnet, Gateway and DNS Server IP addresses. In short, if the new IP you give your computer doesn’t work, chances are someone else on the ISP network has already been assigned that IP address.

Furthermore, you’ll need to move on to the next one and keep trying until you find an open one. Above all, keep in mind that some ISPs internet service match up your MAC or modem data to the address that’s been assigned.  If those 2 things don’t match up, you won’t be able to connect no matter what.

However, if your Wi Fi router assigns the IP and not your computer, you’ll need to http in to your Wi Fi routers interface and manually assign the IP there to be able to change your IP address. Similarly, it’s pretty much the same method as assigning the IP to your computer. To clarify, the method that varies is in how you reach your Wi Fi routers interface. That is to say, you can get the instructions from your manufacturer’s website.

MAC Cloning

What is a MAC address? A MAC address is a physical hardware address assigned to each device that has the capability of connecting to a network. Furthermore, the internet is nothing more than a large network. The MAC address is something that is assigned in the chip on the device and is something the user can change depending on the device.

To clarify, MAC cloning can only be done at your Wi Fi router providing it has those capabilities or has been flashed with software that has those capabilities.  Furthermore, most ISPs assign their IPs based on the MAC address in your equipment. To clarify, if the MAC address of your Wi Fi router is 00-11-22-33-44-55 and you connect to your ISP internet service, the DHCP server records your MAC and assigns an IP.

To clarify, if you disconnect from your internet service, you may lose your IP address depending on their IP lease times. The next time you connect, the DHCP server sees your MAC, looks to see if it has assigned an IP address to you before.

If it has and the lease time has not expired, it will most likely give you the same you had before disconnecting and will not change your IP address. To clarify, this completely depends on how the ISP internet service has their DHCP server set up.

Why Clone a MAC Address?

Getting a new MAC address most likely equals a new IP. To clarify, you’ll need to find the instructions on the Wi Fi routers manufacturer’s website, or flash your Wi Fi router with new software. Therefore, we do not promote flashing your Wi Fi router as you could render it useless if done wrong. We offer a Quick Reference List on our Router Support Relative to IPs page.

Conclusion

If changing your IP address doesn't sound like it's for you, you may use a proxy server or VPN to conceal your true IP address.  To clarify, using private networks along with a private IP address adds more security in your surfing and more advantages.  Most of this article explains the ability to change your IP address from your internet service, from a public IP address.
