Changing IP Addresses
This is my second submission to Astalavista.com, my
first was an explanation of using proxies on IRC. This tutorial will 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 useful because you can change
your ip when you are getting DDoS'ed or if you wish to piss off someone running
a web server (or other service) on your ip range, it is also useful to get
around a bans as long as the ban only covered your ip not your whole ip range.
As usually 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 consider that everything I
mention here is illegal if you are not sure yourself.
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 dns
servers.
1. Getting your IP range - Getting information about your ip range is
not difficult, I recommend using Neo Trace on your own ip. But for our test
just look at your ip address, say it's 24.193.110.13 you can definitely use the
ip's found between 24.193.110.1 < [new ip] < 24.193.110.255, don’t 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 Name Here
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
(NGRPCI)
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
24.xx.xxx.xx
24.xx.xxx.xxx
Lease Obtained. . . . . . . . . . :
Lease Expires . . . . . . . . . . :
This is all the information you will need for now, I suggest 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 usually 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 again 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 usually when you are
constantly getting attempted 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 above.
V. Web servers & Other Services
If you know someone on your ip range is running a web server 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 web server your self.
To "steal" an ip is to basically use the changing ip address method
above and picking an ip that someone that is running a web server 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 until 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 don’t recommend as its pretty illegal,
your isp will get pissed and feds may go ape-shit.
