Does anyone know how to change an IP address? I have an internal IP and I'm pretty sure it's on a long lease so unplugging my router overnight(as I've heard should work)won't.
Things I've tried:
ipconfig/release
ipconfig/renew
also
ipconfig/flushdns
ipconfig/release
ipconfig/renew
I've tried switching over to ubuntu and from there changing the mac address using these commands
ifconfig eth0 down
ifconfig eth0 hw ether de:ad:be:ef:f0:0d
No dice. Any thoughts?

If you want to change your IP simply, you can use any VPN like CyberGhost. :D
-
Well I know how to use IP obfuscators like proxies and such. I'm more looking for a way to change my IP once while working without proxies/vpns/tor. Anyway that's not changing an IP that's simply masking it.
EDIT: I guess it doesn't matter that much the lease expires tommorrow. There doesn't seem to be a way to change the internal IP anyway.

Yes agree.

You say you have an "internal ip" which suggests an ip assigned by a router on an internal network. Changing this ip will have zero effect on your external ip assigned by your isp.
Which you obviously know.....
So assuming your router is also your modem, and rebooting it hasn't worked.
Have you tried calling your isp and talking to them? tech guys are the same everywhere I'm sure if you get the right guy he'll happily discuss there systems and how they can be manipulated into assigning a new ip.
In order for the mac address trick to work (assuming your isp is setup this way) you'd have to use a different modem or hack the mac address on your modem.... an easy way around would just be having 2 modems, pre-configured with your isp credentials and internal network crap, then switch as required.
lol bloody mish installing a new os just to change mac... you know you can use "madmacs" (http://www.irongeek.com/i.php?page=security/madmacs-mac-spoofer)on windows for mac changin.

Haha I already had it dual booted with windows and ubuntu. Otherwise that would be insane. So I can't just change the mac using the two commands I stated in my first post?
-
sure that'll work just add a "ifconfig eth0 up" at the end, and then the mac on your system will be changed.... won't do fuk all to the mac on your modem though.
-
So is that why when I change my mac and then check my IP it's still the same?
-
perhaps :)
Its not illegal to ask your isp to change your ip, just call and talk to them about it and find out how it works.
But certainly if changing the mac was going to work you would have to change the mac on the device that gets assigned the public ip address eg. "your modem" rather than your comp which likely gets its ip from your router.

I see I see. Thanks for the info. I applaud your help
Sorry let me edit this one more time. If I am trying to mac spoof am I correct in saying that there's no need to worry about my modem, and changing it with the ifconfig command will suffice? Even if I am on a shared router network?
Thanks much

No, only your computer's MAC will be visible. The router is only there to route traffic, it doesn't connect to websites directly.
-
So the router network has nothing to do with mac spoofing. Thanks
-
I think the commands you are using only change the mac for that session, if you reboot it will be your ordinary mac again.
Here's a link (http://www.howtogeek.com/howto/ubuntu/change-your-network-card-mac-address-on-ubuntu/) which discusses your options.
-
As far as I remember, MAC address is usualy hardwired into the network card and hence is permanent. If you want to change your mac, just get a new network card.
There are ways to hide it temporarily but I have never seen a permanent sure way to virtually change a MAC addresss. Network cards are very cheep though.
-
MAC's cannot be changed permanently. Only until you reboot... changing it permanently is not worth to do so if it's even possible...

I read through the whole thread but I don't think I grasped what OP is trying to do here. Which one of these two are you attempting to do?
1. Are you trying to change the IP address of your internal network card (one that is physically attached to your computer)?
2. Are you trying to change the WAN IP address that your modem is using from your ISP to connect to the internet?
-
About changing the modem-IP:
A legal way to change the IP of your modem would be to simply reboot it. But this only works if
you have a modem with dynamic IP. As you already tried it,and it didn't work,it seems your
modem isn't supporting dynamic IPs. (To get more detailed info just type the modem IP in
your browser and press enter.)
The second way would be to crack your modem and change the IP this way.
And don't forget:
If you load a page for example,the modem requests the data-packs from the server. If you
change the IP while the modem still loads the data from the server,the server won't know
you changed IP and will still send the data to the (now not anymore existing) IP and not to
your new modem IP,so you won't recieve any data anymore,till you request the data again.

Well I guess since whatsmyip tells me my IP is the same no matter what I do(mac change, trying to assign myself a new IP, ipconfig release, blah blah) then I guess I'm asking about changing the WAN IP
@Area 13- My router does support dynamic IP's so I could just turn off my modem/router/everything and turn it back on and I'd have a new IP?
-
Since your trying to change the WAN IP, you will need to contact your ISP. They are they only ones who can do it without proxy routing.
I worked tech support for a DSL company, and we could change IP's, only if it was DHCP or PPPoE. They do can release/renew from their end called clearing the IP. Another procedure they can do is called a kill/build which kills the circuit between them and you, then rebuild on a different server.
If you where trying to change your LAN IP, then in windows, you can change the IPv4 TCP settings to use a static address instead of the DHCP. You will need to enter a valid IP, with a valid netmask which is usually a class C configuration.
You can also release and renew in the router/modem itself by logging into the web gui.
But as for the external address, your ISP will have to do it.

I had a feeling. It was more of an inquiry than something I was really striving to do I just wanted to know if I could. Thanks
EDIT: I found out my IP lease expired yesterday. Shouldn't that mean that today I should have a new WAN IP? Or is that just for the internal IP
-
If you have a modem with dynamic IP,rebooting it should be as far as I know enough to change the modem IP. 'cause everytime I reboot my modem (wich is also supporting dynamic IP) i get a new IP by my ISP

If you found the lease time doing something like ipconfig then it's your internal ip.
And when the lease expires it doesn't mean 100% you'll get a new IP, because the network stack is pulling IP's from a DHCP pool. You could end up with the same IP every time.
