IP ADRESS haCKING and other info

In here I have figure out some very easy but cool ways to trace out the geographical location and various other infos like ISP details etc of a remote computer using its IP.
Well I guess its one of the most important must learn manul for boys out there if you want to impress your friends particularly gals whom you'll meet online in a chat room and tell them their geographical locations and ISP details and make them surprised and impressed.
In the practical execution of this manual you don't have to work much as it is very simple only you have to use your brain to understand some symbols and some format of expressions and use your IQ to execute things the right way.
What is IP and how to get the IP of a remote system::
Getting the IP or Internet Protocol of a remote system is the most important and the first step of hacking into it. Probably it is the first thing a hacker do to get info for researching on a system. Well IP is a unique number assigned to each computer on a network. It is this unique address which represents the system on the network. Generally the IP of a particular system changes each time you log on to the network by dialing to your ISP and it is assigned to you by your ISP. IP of a system which is always on the network remains generally the same. Generally those kind of systems are most likely to suffer a hacking attack because of its stable IP. Using IP you can even execute system commands on the victim's computer.
Lets take the example of the following IP address: 202.144.49.110 Now the first part, the numbers before the first decimal i.e. 209 is the Network number or the Network Prefix.. This means that it identifies the number of the network in which the host is. The second part i.e. 144 is the Host Number that is it identifies the number of the host within the Network. This means that in the same Network, the network number is same. In order to provide flexibility in the size of the Network, here are different classes of IP addresses:
Address Class Dotted Decimal Notation Ranges
Class A ( /8 Prefixes) 1 .xxx.xxx.xxx through 126.xxx.xxx.xxx
Class B ( /16 Prefixes) 128.0 .xxx.xxx through 191.255 .xxx.xxx
Class C ( /24 Prefixes) 192.0.0 .xxx through 223.255.255 .xxx
The various classes will be clearer after reading the next few lines.
Each Class A Network Address contains a 8 bit Network Prefix followed by a 24 -bit host number. They are considered to be primitive. They are referred to as "/8 ''s" or just "8 's" as they have an 8-bit Network prefix.
In a Class B Network Address there is a 16 bit Network Prefix followed by a 16 -bit Host number. It is referred to as "16's".
A class C Network address contains a 24 -bit Network Prefix and a 8 bit Host number. It is referred to as
"24's" and is commonly used by most ISP's.
Due to the growing size of the Internet the Network Administrators faced many problems. The Internet routing tables were beginning to grow and now the administrators had to request another network number from the Internet before a new network could be installed at their site. This is where sub- netting came in.
Now if your ISP is a big one and if it provides you with dynamic IP addresses then you will most probably see that whenever you log on to the net, your IP address will have the same first 24 bits and only the last 8 bits will keep changing. This is due to the fact that when sub-netting comes in then the IP Addresses structure becomes:
xxx.xxx.zzz.yyy
where the first 2 parts are Network Prefix numbers and the zzz is the Subnet number and the yyy is the host number. So you are always connected to the same Subnet within the same Network. As a result the first 3 parts will remain the same and only the last part i.e. yyy is variable.
****************** *****
For Example, if say an ISP xyz is given the IP: 203.98.12 .xx Network address then you can be awarded any IP, whose first three fields are 203.98.12 . Get it?
So, basically this means that each ISP has a particular range in which to allocate all its subscribers. Or in other words, all subscribers or all people connected to the internet using the same ISP, will have to be in this range. This in effect would mean that all people using the same ISP are likely to have the same first three fields of their IP Addresses.
This means that if you have done a lot of (By this I really mean a lot) of research, then you could figure out which ISP a person is using by simply looking at his IP. The ISP name could then be used to figure out the city and the country of the person. Right?
