Change Your IP in less than 1 min.

1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "command" and hit ok
You should now be at an MSDOS prompt screen.
4. Type "ipconfig /release" just like that, and hit "enter"
5. Type "exit" and leave the prompt
6. Right-click on "Network Places" or "My Network Places" on your desktop.
7. Click on "properties"
You should now be on a screen with something titled "Local Area Connection", or something close to that, and, if you have a network hooked up, all of your other networks.
8. Right click on "Local Area Connection" and click "properties"
9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
10. Click on "Use the following IP address" under the "General" tab
11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).
12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
13. Hit the "Ok" button here
14. Hit the "Ok" button again
You should now be back to the "Local Area Connection" screen.
15. Right-click back on "Local Area Connection" and go to properties again.
16. Go back to the "TCP/IP" settings
17. This time, select "Obtain an IP address automatically"
tongue.gif 18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address
With a little practice, you can easily get this process down to 15 seconds.

Warning:
This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back

reply if u found it knowledgeable coz i need response.....!!

Change MAC address of you Network Adaptor

Although physical MAC (Media Access Control) addresses are permanent by design,

several mechanisms allow modification, or "spoofing", of the MAC address that is

reported by the operating system. This can be useful for privacy reasons, for instance

when connecting to a Wi-Fi hotspot, or to ensure interoperability. Some internet

service providers bind their service to a specific MAC address; if the user then

changes their network card or intends to install a router, the service won't work

anymore. Changing the MAC address of the new interface will solve the problem.

Similarly, some software licenses are bound to a specific MAC address. Changing

the MAC address in this way is not permanent: after a reboot, it will revert to the

MAC address physically stored in the card. A MAC address is 48 bits in length.
As a MAC address can be changed, it can be unwise to rely on this as a single method

of authentication. IEEE 802.1x is an emerging standard better suited to authenticating

devices at a low level.

Mac OS X
Under Mac OS X, the MAC address can be altered in a fashion similar to the

Linux and FreeBSD methods:
sudo ifconfig en0 lladdr 00:01:02:03:04:05
or
sudo ifconfig en0 ether 00:01:02:03:04:05
This must be done as the superuser and only works for the computer's ethernet card.

Instructions on spoofing AirPort Extreme (2.0) cards are available here. There are not,

as of yet, any known ways to spoof original AirPort (1.0) cards.
The AirPort Extreme MAC address can also be changed easily with SpoofMac.
Windows
Under Windows XP, the MAC address can be changed in the Ethernet adapter's

Properties menu, in the Advanced tab, as "MAC Address", "Locally Administered

Address", "Ethernet Address" or "Network Address". The exact name depends on the Ethernet driver used; not all drivers support changing the MAC address in this way.
However, a better solution - requiring Administrative User Rights - is to pass over

the System Registry Keys under

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}.

Here settings for each network interface can be found. The contents of the

string value called 'NetworkAddress' will be used to set the MAC address

of the adapter when next it is enabled. Resetting the adapter can be accomplished

in script with the freely available command line utility devcon from Microsoft,

or from the adapters context menu in the Network Connections control panel applet.
There is a nice tool to change the MAC address for all cards (even those that can't

be changed through the adapter's Properties menu): SMAC MAC Address Changer
Note: to check your MAC address easily on a Windows XP box, go to Run, type CMD,

then type "ipconfig /all" without quotation in the command prompt. The number under

physical address is the MAC address. If multiple IP are displayed, you should look

under the label "Ethernet adapter x", where x is the name of your connection

(which is Local Area Connection by default).

Router
The method to change the MAC address of a router varies with the router.

Not all routers have the ability to change their MAC address. The feature is

often referred to as "clone MAC address". This take the MAC address of one

of the machine on your network and replaces the router's existing MAC address

with it. Some support the option to manually enter the MAC address.

How to change the IP address of your computer

How do I change my IP address?" and "Can I change my IP address?"

are probably the most commonly asked questions.

Please attempt the following then, if that does not work,

visit the Change IP Address forum.

Before trying any other methods to change your IP address,

try turning off (or unplugging the power of) your Cable/DSL modem for five minutes.

In many cases this will change your IP address.

However, if that does not change your IP address,

repeat the process for 8 hours (overnight works well)

instead of 5 minutes. Hopefully this will result in an IP change.
If the above does not result in your IP address changing,

please look through the below for the situation that best

matches yours and attempt to change your IP address that way.

Unfortunately you are not able to get your IP address to change

in all cases, as it is ultimate determined by your

ISP's DHCP configuration (when you've got a dynamically assigned IP address, that is.)

Windows - Computer connected directly to the modem

2. Type "ipconfig /release" (without the quotes, on the command line by itself).
3. Type "ipconfig /renew" (without the quotes, on the command line by itself).

Windows (second option) - Computer connected directly to the modem

1.Get to a command prompt. (START, run, cmd).
2.Type "ipconfig /release" (without the quotes).
3.Shut down computer.
4.Turn off computer.
5.Turn off all ethernet hubs/switches.
6.Turn off cable/DSL modem.
7.Leave off overnight.
8.Turn everything back on.

Network with Router
1.Log into the router's admin console. (Often http://192.168.1.1/)
2.Release the IP address. (Method varies by router manufacturer)
3.Turn off router, ethernet hubs/switches, and the cable/DSL modem.
4.Leave off overnight.
Turn everything back on.

If you are using a cable/DSL modem and a router, you may wish to

connect your computer directly to the cable/DSL modem.

Please note that this could significantly impact your system security.

This allows your ISP's DHCP to issue you a new (hopefully changed)

IP address based of the (hardware) MAC address of your computer's ethernet card.

If all the above has not worked to change your IP address and

you have a router, check and see if there is a "Clone MAC Address" option.

Using it should change your IP address; however, you'll only be able to do it once (in most cases).

These will not work in all cases. If all else fails contact your

internet service provider (ISP) and ask them if they are able to

change your IP address or how long your connection needs to be off for your IP address to change.

If you trying to change your IP address because you are just trying to access web based forums you may wish to attempt to configure your internet browser to use a proxy server.FAQ: What is a proxy server?FAQ: How do I use a proxy server?

If this does not answer your question, please visit the change IP address forum.
We've heard about IP Changer programs, but have not seen any that work in a reliable manner. If you have seen an IP address changer program that works, please let us know.
