IP Address
« on: April 01, 2012, 04:26:40 am »
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.

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" 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 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...
