Your IP address is assigned to you by the server at your ISP. You can't change it (tho some servers are dynamic, and you get a new IP address everytime you logon to the Internet). Are you thinking of something else perhaps?

go to my network places>right click on it> chose properties> open up LAN CONNECTION> highlight INTERNET PROTOCOL> then click on PROPERTIES> make sure you chose OBTAIN AN IP ADDRESS AUTOMATCIALLY & OBTAIN DNS SERVER ADDRESSES AUTOMATICALLY. from there you should get a new IP address if you're using a CABLE ROUTER.

You can change your IP by re-installing Windows from time to time.
I do this quite offten on a computer that is only for the internet. When I get to much trash on it, spyware, wiruses, trojans etc...I am just reinstalling Windows and all the hackers in the world can kiss my ass

[guns1inger]

It is still allocated by either yur ISP or your router. Re-installing Windows is a), needlessly drastic and over dramatic, and b) a waste of time in this instance. If your ISP is allocating your IP address dynamically, you can usually get a new IP address by simply opening a command prompt and typing

ipconfig /release <enter>
ipconfig /renew <enter>

This releases your current IP address back to the pool, and then requests a new address. Depending on lease periods etc set at your ISP's end, you may or may not get the same address back.

Of course, if your router is giving you an IP address, all this is pointless.

[AlanHK]

Open your browser at http://myip.dk. That will display your current IP. If you're using an external modem or router, turn it off for a few minutes, then back on. Your system should reconnect. Refresh the webpage to see if your IP has changed. it probably, but not surely, will be different if your ISP has reallocated your old one.

There are various ways to do this in software, but they depend on exactly what method your're using to connect. A small utility called IsItOn displays your IP and can break your connection.

I have recently been wondering this myself, as I have upgraded from 3mb/256 to 5mb/512 yet it has been over a month, and no speed change. I have called and email my isp several times, with no luck.

They keep suggesting that I have to do something on my end, but I am doubtful. I have tried there suggestions, short of a reinstall and forcing an IP change, which I can not seem to do, no matter what I try. Even after an 8 hour blackout (storm, took out cable, power and everything) I still got the same IP.

Anyways, sorry for the long post, and I hope I didn't hijack this thread. I just felt I had to comment on this.

[guns1inger]

DHCP has a concept of leases. Basically you are 'leased' an IP address for a period of time. This could be a few minutes, or months. If you ISP has the leases set for an extended period, it is highly likely that you will get allocated the same IP address every time you connect, for months potentially. Even a release and renew might not get you a new address.

[gadgetguy]

Why do you want to change your IP address? Are you unable to access the internet? Do you have a home network and can't get it to connect to your other PCs?
Most PCs get the IP address from an DHCP server but it is also possible to manually set it. If this garage sale computer was part of a home network it may have been manually set. If so, follow budz advice. If you want to manually change it to comply with a home network follow budz advice but don't choose "obtain automatically" but instead enter what you want it to be in "Use this IP instead". This, of course, means that you have to keep track of your assigned addresses so you don't assign duplicates.
Also on a home network if you are having trouble connecting to other PCs it may not be the IP address that's the problem. XP has a built in firewall that may be keeping you from seeing the other PCs, (or seeing it from the others).

That is a good idea but beware you reinstall windows too many times and you will wind up calling Microsoft for permissiion to restart the computer and verifying the key that is on that system - It has happend to me several times.

[lordsmurf]

Why do you want to change your IP address? ... from an DHCP server

Change the MAC address of the router or NIC.

I'm on cable connection and this doesn't change my IP.

I do not waist much time re-installing windows, I have a back up hard drive which always have a fresh copy of windows installed. Everytime something goes wrong I just swap the hard drives and than when I got some spare time I'll take care of the mess up hard drive.

This is only true if you need to install some new updates. I never update anything. I believe it is a waste of time and automatic updates only changes my personal settings. I just turn off automatic updates and when I really need to update something I do this manually.

[redwudz]

Some ISPs, mine included give you a fixed address. It depends on the ISP. I've had the same address for several years, no matter how many times the cable modem is unplugged.

BTW, if you had your ISP change your connect speed, you might want to reset your cable modem by unplugging it from the power supply for a few minutes and force a reset. I have to do this occasionally when they send a bunch of 'upgrades' to it over the cable and my speed drops off. (But I still get the same address. )

I have my router and computer set up for fixed LAN addresses, which may be dblue's problem. If so, just change the LAN settings to 'Obtain an IP address automatically' as budz mentions. I set them in Internet Protocol (TCP/IP) Properties.

[gadgetguy]

OK, we're starting to echo each other. Where is that OP?

[Skith]

The my ISP said forcing a change in my IP might enable the speed change. Powering off, resetting the modem, computer and router all at once didn't help. They were powered off for several minutes.

I will try lordsmurf's suggestion.

The OP post was on how to change a computers IP, I hope I haven't deviated from that. If the OP or a mod feels it has, then the thread could be split, and I appologise.

i got here



is there a apple botton or something like that?

[budz]

You'll need to fill out the section where it says USE THE FOLLOWING IP ADDRESS if you're going to set a specific IP number. If you're not then just use the OBTAIN AN IP ADDRESS AUTOMATICALLY.

[redwudz]

dblue, what's your internet connection? Cable, DSL or Dialup? Do you have a router? I would look at your other computer in the same place that budz mentions. You should see your present settings there. Your new computer should use about the same, except for your IP address.

Most of the time the 'Obtain IP address automatically' works. If it doesn't and you have a router, you may have to set a new address in the router and put it into the computer manually.

Networking can be problematic at times. If all else fails, uninstall the NIC card in Device Manager and reboot. Have the NIC driver available. Then you may be able to use XP's networking wizard to set everything up.

I've managed to get it so messed up before that reinstalling XP was the easiest solution. All it takes is to have several networking problems all at the same time and it can be very difficult to fix. And you don't know what changes the previous owner did to the network settings.

D-LINK router

is there a program that can change the IP in the router? would that work?

[gadgetguy]

D-Link makes many routers, which model do you have?

Undoubtedly the IP address in the router can be changed, but if it supports DHCP then your computer should be getting a unique address from the router already. Going back to earlier questions... Why do you want to change the address? What problem are you having that you think will be solved by changing the address?

[CrayonEater]

Type into the address bar of your browser: 192.168.0.1

Enter your username and password to log into the router

Look under Status and note your IP address and DNS server addresses.

1. If you want to change your public IP, click WAN.

1.1 If you are set to Static IP, ask your ISP for a new IP, subnet mask (this is usually 255.255.255.0), gateway address, and DNS server addresses and enter them here. Your DNS addresses usually stay the same though there are some exceptions.

1.2 If you are on a dynamic IP, look at MAC address. It is 12 digits e.g. 00-05-1a-cc-31-3b. Write down the MAC address currently in there (in case you need to revert back to it later - some ISPs "register" your MAC address and do not want you changing it without prior notice). Type in a new one, with the first two digits usually "00" though that is not required and click APPLY.

Unplug or turn off your cable/DSL modem for a few seconds and plug it back in. Let it reboot. Then do the same for your router.

Look under Status and you should have a new IP.

2. If you want to change your LAN IP, click LAN
This is the base address of your router. I do not recommend changing it, unless you know a bit about reserved and private addressing and such.

Click DHCP.

Select Disabled or set the IP range to something other than what you want your PC to have. The ending range must be from 2-254; you cannot use .0, .1, or .255.

On your PC, click Start->Control Panel->Network and Intenet Connections->Network Connections->LAN->right-click Properties->TCP/IP and select Use the following IP address: Enter in for the IP address 192.168.0.x where x is something not in the range you specified above and not .0, .1, or .255. subnet mask is 255.255.255.0, and gateway is 192.168.0.1 (this is the base address I recommended not to mess with earlier). Also make sure you don't assign two devices the same IP address.

In the use the following DNS server addresses field below, enter the DNS server addresses you wrote down from the router's Status screen I mentioned at the beginning.

Click ok when done.

[redwudz]

dblue, check your other computer that's working on the internet and see if it is also set to 'Obtain an IP address automatically'. If so, you should be OK with that setting. Run the 'Repair' while you are there as it sometimes helps.

You can access your router as mentioned by typing 192.168.0.1 into a web browser. See if your router is set to supply IP addresses automatically. It should be shown on the DHCP page. If it's set to supply them automatically, no addresses will be listed.

For D-Link routers, you can go to their homepage: http://support.dlink.com/products/ You can pick yours from the list or use the 'quick find' at the top right. Then you can DL your product manual if you need it. It will tell you all the steps to set up your DHCP specific to your router. I have a D-Link, DI-704, a DI-704UP and a DGL-4100.

If the computer is still not seeing the router, then there may a problem with some of the NIC card settings or network settings in that computer. You can try uninstalling the NIC in Device manager, reboot and then reinstalling it. That may reset it. You might want to have the NIC driver handy when it reinstalls.

One other thing you can try is to bypass the router and plug the computer directly into the cable modem. Make sure the computer is set for automatic IP addesses. That will simplify trying to figure out the router settings. If it works there, then the router needs to be set up.

If still no go, run the 'Network Setup Wizard' in Control Panels. It can often reset the connection. The previous owner of the computer may have really messed up the networking. (I've done it myself in the past. ) Usually reseting everything works, but if it's really messed up, I have resorted to reinstalling the OS and that always works.

[lordsmurf]

192.168.0.1 does not work on all routers. Read your book that came with it. Also, it's possible to change your router address (although 192.168.*.* should be the format).

[budz]

Lordsmurf is correct that not all routers use 192.168.0.1. Long ago a Linksys techie told me that for Time Warner Road Runner users it was best to use 10.10.10 instead of 192.168.0.1. I replaced a cable router a few months ago and changed the router IP to 10.10.10 and it works fine.

What problem are you having that you think will be solved by changing the address?

I think this is the real question that needs answering here.

It's also still not clear if he's talking about a LAN IP or an Internet one.
