Changing IP Addresses
This tutorial will teach teach you how to change your ip address to any
other one on your ip range instead of having your DHCP Server pick one
for you. This is very usefull because you can change your ip when you
are getting DDoS'ed or if you wish to piss off someone running a webserver
(or other service) on your ip range, it is also usefull to get around
a bans as long as the ban only covered your ip not your whole ip range.
As usualy anything illegal you do while reading
this tutorial or after reading this tutorial is not my fault, your actions
are your own so don't blame me. I do not claim that the things I teach
are legal, so concider that everything i mention here is illegal if you
are not sure your self.
II. Needed Information
Before you can change your ip you need some information. This information
includes your ip range, subnet mask, default gateway, dhcp server, and
1. Getting your IP range - Getting information about your ip range is
not difficult, I recomend using Neo Trace on your own ip. But for our
test just look at your ip address, say it's 18.104.22.168 you can definetly
use the ip's found between 22.214.171.124 < [new ip] < 126.96.36.199,
dont use x.x.x.1 or x.x.x.255. To find your ip simply open a dos/command
prompt window and type ipconfig at the prompt, look for "IP Address.
. . . . . . . . . . . : x.x.x.x".
2. Subnet Mask, Default Gateway, DHCP Server - These are very easy to
find, just open a dos/command prompt window and type 'ipconfig /all' without
the ' '. You should see something like this:
Windows IP Configuration
Host Name . . . . . . . . . . . . : My Computer
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : xxxx.xx.x
Description . . . . . . . . . . . : NETGEAR FA310TX Fast Ethernet Adapter
Physical Address. . . . . . . . . : XX-XX-XX-XX-XX-XX
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 24.xxx.xxx.xx
Subnet Mask . . . . . . . . . . . : 255.255.240.0
Default Gateway . . . . . . . . . : 24.xxx.xxx.x
DHCP Server . . . . . . . . . . . : 24.xx.xxx.xx
DNS Servers . . . . . . . . . . . : 24.xx.xxx.xxx
Lease Obtained. . . . . . . . . . : Monday, January 20, 2003 4:44:08 PM
Lease Expires . . . . . . . . . . : Tuesday, January 21, 2003 3:43:16
This is all the information you will need for now, I sugest you either
keep your dos/command prompt window open or copy & paste the information
somewhere, to copy right click the window and select text and click once.
III. Changing your IP Address
To change your ip address first pick any ip you like out of your ip range
and remember it or write it down. It is usualy a good idea to make sure
the ip is dead (except for what we are going to do later on) so just ping
it via "ping x.x.x.x" and if it times out then you can use it.
Now go to My Computer, then Control Panel. In Control Panel select Network
Connections and pick your active connection, probably Local Area Connection
or your ISP name. Open that connection by double clicking on the icon
in Network Connections, then select Properties under the General Tab.
In the new window that pops up select Internet Protocol (TCP/IP) and click
properties, it's under the general tab. In this new window select the
General tab and choose "Use the following IP address" and for
the IP address enter the ip you would like to use (the one you picked
from your subnet earlier) and for the Subnet Mask enter the subnet mask
you got when your ran ipconfig /all, same goes for the Default Gateway.
Now select "Use the following DNS server addresses" and enter
the information you got earlier. Now just click OK. Test that it worked,
try to refresh a website and if it works you know everything is okay and
you are connected. To make sure the change worked type ipconfig agein
and the ip address should have changed to your new one.
IV. DDoS & DoS Protection
If your firewall shows that you are being ddosed, this is usualy when
you are constantly getting atempted UDP connections several times a second
from either the same ip address or multiple ip addresses (ddos), you can
protect your self by changing your ip address via the method i described
V. Webservers & Other Services
If you know someone on your ip range is running a webserver and he or
she has pissed you off or you just like messing around you can "steal"
their ip address so any dns going to that ip will show your site instead
because you would be running a webserver your self.
To "steal" an ip is to basicaly use the
changing ip address method above and picking an ip that someone that is
running a webserver has in use. Often you will be able to keep that ip
at least for some time, other times you wont be able to use it so just
keep trying untill it works. You your self will need to have a web server
on the same port with your message. You can do this with other services
too. You can also DoS or DDoS the ip address you are trying to steal to
kick him off the net, but I dont recomend as its pretty illegal, your
isp will get pissed and feds may go ape-shit
