How-To: Change Your IP Address in Windows

Note: This procedure changes the IP address of a computer on a wired or wireless network. If you want to change the IP address of your internet connection, you should contact your service provider, as they're the ones who exert control over this.



To change your network IP address in Windows XP, Vista, or 7:

1. Press the Windows Key and R

2. Type command and press Enter. This loads your DOS prompt

3. Type ipconfig /release then press Enter. This disables your internet connection

4. Go to your desktop, and right-click on something called Network Place or My Network Places (If you're using Windows Vista or 7, look for the Network and Sharing Center through Control Panel)

5. Click Properties. You should now see something called Local Area Connection or something similar

6. Right-click on your connection (titled Local Area Connection if you're using an ethernet cable or Wireless Network Connection if you're on WiFi) and click Properties

7. Under the General tab, double-click on the Internet Protocol (TCP/IP)

8. A new window appears. On its own General tab, click the box beside Use the following IP address

9. Type in ones until you fill the box up (it should read 111.111.111.111)

10. Press Tab. You'll notice the Subnet Mask section automatically fill sup with numbers

11. Click OK

12. Click OK to bring you back to the "Local Area Connection" screen

13. Right-click Local Area Connection and Click on Properties again

14. Again, under the General tab, double-click on the Internet Protocol (TCP/IP)

15. Select Obtain an IP address automatically

16. Click OK

17. Click OK

18. Go back to your DOS prompt, type "ipconfig /renew" and press Enter. This restores your internet connection.

By now, the network should've assigned a new IP address to your computer automatically.

Hi,

I am a Newbie here, and as gone through your post, I found this procedure very applicable. Basically, for securing our data we need to change the IP address.


There is also another way to change an IP address, by placing Proxy IP address and this can be done by going through tools then options, advance tab, then click on settings, check on manual proxy configuration and fill the proxy IP and then ok.


By this you can change your IP address to Proxy IP.


Thanks!!

Won't ipconfig /release and the ipconfig /renew work just the same or are you coming from a security point of view where users sometimes don't have permissive rights to carry out this operation in windows CLI

Why go through the properties of TCP in network center? Or am I missing the point, its late and I've ate too many chips.

I always change my ip this way on windows xp but now since ive updated to windows 7 I try to change my ip and it always stays the same its driving me crazy any help why ?

hey! thanks fo the reply though late..:-)
okiee so u r saying that the ip address that we change is the logical ip..rite
so what's the physical ip of a computer(is it the MAC-address)??
its true that we r changing the logical ip address..bt it is nt the ip that iz transferred over the net..cz if i chck the ip in the mails its nt the same as logical ip f my pc..its f sm othr series..

am i rite or m missing sm details???????

No, the IP adress is given to you for the ISP and this IP is dinamyc. In some case (LAN) you can change the IP for another, BUT this is 'cause the range of IP isn't public, is private.

O this is exactly what the local networking guy does on my machine. Now I no longer need to call him in case I run into any IP related networking trouble so thanks.
