What is an IP address?

An IP address or Internet Protocol is a 32-bit number address, which isassigned to each computer (technically called a host) connected to the Internet. It is the address to which different types of data are sent to your computer. It consists of 4 octets. Each octet equals 8 bits and has a range from 0 to 255. (Every IP address on the Internet is sectioned off into classes from class A to class E, depending on a different range of numbers). Well I always believed that sometimes pictures speak louder than words so here is an example of a typical IP address:


189.134.221.61


| | | |

| | | |---------> (4th octet. 8-bits. Ranges from 0 to 255)

| | |-------------> (3rd octet. 8-bits. Ranges from 0 to 255)

| |-----------------> (2nd octet. 8-bits. Ranges from 0 to 255)

|---------------------> (1st octet. 8-bits. Ranges from 0 to 255)

    There are two IP address:
    1)Public ip address(Static and Dynamic)
    2)Private or Local Ip address

    Public IP address:
    It is the one provided to you by your ISP.This is the address which will be visible in the internet.It can be found by visiting sites like IP-Details.com .

    Private IP address:
    Private IP addresses are typically used on local area networks like School,College,etc.,It can be found by Start->Run->Cmd->type "ipconfig" and enter.
