hmmmm....here's a interresting question that somehwat has something do to with the current topic...I have heard of people forging their ip address' so that when somebody looks up your ip it will show whatever you want it to show....Is this possible...And if so does anybody know any information on it?

Mine changes automatically.

you mean IP spoofing ?
amungst other things, an IP packet contains a "from address", a "to address" and "data"

you need "root" or "super user" access levels, but it is possible to manually construct an ip packet, and lie when you insert the "from address"

meaning when your packet is sent, the reciever will think it came from a different place.

unless you are planning a DOS attack, you can only forge your address with protocols ICMP, UDP and IGMP.

the TCP protocol is a connection protocol, if you forge your from address, the reply to the connection attempt will be sent to the wrong address, the handshake never made, and no connection opened.

here's an old example... the orginal Quake server from ID software had a backdoor.
the backdoor would follow instructions sent to it from ID software's IP address range over a UDP port.

it was possible to send instructions to quake servers, forging the from address to ID software's IP address.

All that means is that it changes the IP address on your LAN and not on the internet in case anyone gets confused.

and is totally useless..

Precisely.
If you want to hide your real IP address on the internet, use an high-anonmity proxy.
However, note that will greatly reduce your speed.
My DSL line is 512/128, but after passing through and local proxy, a speed test returned an speed of about 200kbps, whereas it normally returns 434kbps.

To change the IP address for your Internet connection you have to change the IP address for the router or modem. On a DSL or Cable modem (I’ll use modem for short) the IP addresses are dynamically assigned and can change when the lease is up or when your ISP forces a change, this is unless you pay for a static IP address.

To see what your modems IP address are you can do a trace route from the command prompt or go online to a site that will show your IP address. Like: Click here to see the IP address you show on the internet.

Now you can log off the Internet, turn off your modem, wait 5 minutes and turn it back on. If you go back to the same site you will see if the IP address changed or stayed the same.

So changing the IP address on your computer may not change your Internet IP address. If you do an “ipconfig /all” at the command prompt you will see the windows configuration and IP address for that computer. Most but not all of the time the first octet of your IP address will be 10, 172 or 192 (this are fake none-routable IP addresses)

So if your computers IP address and the IP address that you show to the Internet (use previous link to test) is not the same then that whole change of the computers IP address are for nothing. On the other hand if you are creating a home network and would like to have control over what IP addresses each computer have then you can assign your own IP addresses. Make sure you use an IP range that is not commonly used for the Internet. You can create a class A, B, or C network at home and the NAT (Network Address Translation) will translate the “fake” non-routable into a routable address (your modem’s IP address)

If you think about the modem as the dividing point between you and the Internet then you control everything on the inside. This is your network and you can lay it out and assign IP addresses, as you like. From the modem to the internet are controlled by your ISP and the initial setup registers the MAC address for that modem and the ISP assign you an IP address from their dynamic IP space.

Yeah, thats already been ssaid atleast twice i think in this thread.

why hide your real ip?
even how many times to change it you are still traceable

heheheeheh. My ip changing technique is the most easiest.

look first u need to have a local area connection.
then u need a sofware called x sharez scanner.
the u need another software called smac.

procedures are now.

that first u open xsharezscanner then enter ip range then hit scan .
u will be provided with some mac addresses.
enter one of the mac address in that program called smac. your current mac address vll be changed to the other only when u hit change button.
last and final step is to disable and enable the connection from the netwoprk places. thanks
