Change My IP Address

[briang959]

The best way to try and change your IP address is to unplug your modem and plug it back in. Do you have a new IP? If not, unplug and leave it unplugged for several hours and plug it back in. Do you have a new IP yet? If you still don't have a new IP, you may need to unplug your router at the same time you unplug your modem. Some ISPs reassign IPs via DHCP servers at certain time intervals. They also can lock you in to an IP via your MAC address. If your router allows you to clone a MAC address, you can also try doing that in order to get a new IP from your ISP.



If anyone else has suggestions, please add them.

And just turn the protector off when you want to disconnect. I usually do it first, then turn off my laptop. Works great, saves electricity and the bother of unplugging the cables. Remember to turn on the protector with the DSL modem and router before starting up your computer - it seems to work better that way.

In fact, I have everything that does not have to be on all the time, such as my external hard drive, my speakers, my USP hubs, my external DVD recorder, and light, also on a surge protector that I turn off when not using my computer. Cuts electricity usage.

My IP address is always different when things are turned on after being off all night. The only problem is that if there is another computer that is asleep on the network, sometimes an IP conflict will happen if someone wakes it up. Reboot them to fix that, or wake up the sleeping one before starting the one that is off.

I'm surprised that you have an IP conflict when you wake a sleeping machine. On my network, the external (WAN) IP address changes when I reboot the DSL modem. I happen to use fixed IP addresses on the internal (LAN) network and those avoids IP conflict issues. However, I'm fairly confident that if I used the DHCP server on the router, I wouldn't have IP conflict.

Do you have a router with a DHCP server?

I agree with clanmills. If you have DHCP, or you assign statically, you shouldn't have an IP conflict when waking a computer.

perhaps the computer waking up is configured static, and while it's off, something else is being assigned it by DHCP

If you are trying to change your Internet IP address and are changing your modem's MAC address to accomplish that, you may run into issues with your ISP not allowing you to connect.

I know that my ISP registers my MAC, and it's not very easy to change my IP. I know for certain if I swap modems and call to register the replacement, I will be assigned a new IP. I don't have a static IP, but it doesn't change often... although I do leave the connection on 24/7.

I beleive you can change IP by using the Network Connection via Local Area Connection. Does anyone know how? If so post it here on this thread.

If you're using a dynamic IP address, (this is the usual and windows calls it 'Obtain and IP address automatically'):
On XP, I believe you can use Control/Network to do this. Select the connection (probably called LAN or something like that). Right-click/Repair. This will tear down your connection to your IP and recreate it. You'll probably be assigned a different IP address by your ISP. Or use the dos command ipconfig/renew.

However this doesn't necessarily guarantee you a new IP address - you may be assigned the same one again by your ISP! In which case, disable the connection for a while and then enable it. With a bit of luck, you'll now have a different address.

If you're using a static IP address (this is quite unusual):
On XP, use the Control/Network. Select the connection, open Properties, TCP/IP and configure as necessary.

this is true, but entirely depends on the DHCP lease time from your ISP

some ISPs are known to set the lease time to like.. .1-1.5 years...

i suppose it is possibile to do an ipconfig/all command and see the lease time, if your computer is not behind NAT

Any video? This is hard.

1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "cmd" and hit ok

You should now be at an MSDOS prompt screen.

4. Type "ipconfig /release" just like that,without quotes 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"
18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address
