how to find the ip address of a website

well ....the ip address or the internet protocol is basically a 32-bit number that uniquely identify a
network or host or anything ranging from very small to very large.
it is divided into four parts ecah part consists of an octet.that is separated by dots .

suppose i have an ip of: 192.168.123.132

its binary form:110000000101000111101110000100..

well now lets divide it into four parts  :11000000.10101000.01111011.10000100. 


basically when you look into an ip address you must be able to figure out what does that weird no. displaying in your cmd(generally) means ...well the again we divide the ip address into two parts :
192.168.123:is the network address 
and the last part 132: is the host address.

now something every one should know that ..there are all total 3 classes of networks

1) class A network ,which has a subnet of 255.0.0.0
2) class B network ,which has a subnet of 255.255.0.0
3) class C network ,which has a subnet of 255.255.255.0

they vary according to network topology

now how do you find an ip address of a web site???

1) open the cmd (command prompt)
2) type in : ping www.google.com ( lets say the target website is google,its all according to you)
3) press enter,then you will get some command lines running down,its your network trying to connect the google 
   server,after 4 or 5 steps,it terminates and shows you the ip address (with 0% data loss)

now ,you can do what ever you want ....   :)
