What is IP address ?.



What is IP address ?.

                                      
Each computer connected to the Internet has a unique identifying address or address. To that address Is called IP (Internet Protocol) address. IP addresses are unique and two The IP address of a computer cannot be the same anywhere.
IP Address is a 32 bit number. Decimal numbers in four parts using three decimal places (.) The IP address is written. There are eight Bits per section. Each part of this is known as Octate. The value of each number in the IP address can range from 0 to 255!
example :-  192.168.1.2

This IP address can be found by publishing it in binary for the computer.

11000000     .      10101000       .       00000001      .     00000010
   (192)                    (168)                       (1)                        (2)

The first IP address created using numbers from 0 to 255 is 0-0-0-0 and the last IP The address is 255.255.255.255. Each IP address has two parts. The first one is Net ID and the second one Host ID. Net ID is a network that is compromised and Host ID is the one connected to that network The host computer is a mess.
For example:- for 192.168-12, 192.168.1 is the Net ID and 2 is the Host ID. IP Addressing Box More than 429 million computers can be connected to the Internet.
Advantage:
1. Since IP addresses are unique, it can easily access every computer connected to the Internet (Identify) can be done.
2. IP addresses are easily accessible to cyber criminals.
Disadvantage:
1. IP address is a difficult thing to remember. So remember to use the URL system to remember the IP address The difficulty is overcome.
IP Address Classification / Classes:
The first one or more of the four Octate IP addresses is used as the Net ID and The rest are used as Host IDs. On the number of Octate used for Net ID Based on this, the class of IP addresses is created. The main three classes are: 1. Class A, 2. Class B and 3. Class C

1. Class A IP Address:
This category uses the first Octate for the Net ID and the remaining three for the Octate (eightbit) is used for Host ID. The first of the 4 bits is always assumed to be '0'. The rest are 7-bits With the help of this, the Met 27 = 128 Net ID can be created. Of these, 2 are Net ID's for specific purposes Reserved. As a result, Class A may have 126 networks. To grow Class A class network is used for organizations.

2. Class B IP address:
In this category use the first two Octate for the Net ID and the second Octate for the Host ID. Is done That means using the first 16 bits for the Net ID and the last 16 bits for the Host ID. Either. The first two of the first 16-bit are always assumed to be 10. The next 14-bit is in the Class B address Is done In this case, the Net 24 = 16384-Net ID is available. On the other hand, the last 16-bit bits 2 = 65536 Host ID available. Class B network is used for medium quality organizations.

3. Class C IP Address:
The first three Octate for Net ID in this category and the last 0etate for Host ID are used Is done That is, in this case the first 24 bits for the Net ID and the last 4 bits for the Host ID are used. The first three of the May 24-bit are always captured at 110. Next, create a Class C address with 21 bits. Either way, so the MET 22 = 2097152-Net ID is available. On the other hand, 25 with the last bit. 256 Host IDs are available. Class C IP addresses are suitable for short network; Where According to 950 hosts, Host Computer can be connected to the network.
                                                            
                                 
* Subnet Masking:
Subnet masking is a technique that uses the heist part of an IP address. The Host Part is then broken down and subnet is created. One of the heist addresses in this case A subnet can be identified by storing the part in a corner. The following is a simple diagram showing the technique of breaking down a heist and creating a subnet mask:
The network mask on IPv4 (Internet Protocol version 4) is made up of 32 bits. The one on the right-hand side The block of bit. (Octate) is expressed as zero (0) and the remaining 24-bit on the left is expressed by T. Is done In this case the '0)' block to the right is used as Host Identifier. The table below lists IP Network 192.168-69 Network Prefix and Host Identifier separation And shows the structure of the corresponding Network Mask (255.255-255-0)

                                                       Binary Form                                         Dot-decimal notation
IP Address             11000000: 10101000 • 00000101 00001001                     192.168.5.9
Subnetmask          111111111111111111111111: 00000000                          255 .255 . 255.0
Network Prefix     11000000: 10101000 00000101: 00000000                       192.168.5.0
Host Part               00000000 00000000 - 00000000. 00001001                         0. 0. 0. 0

Registered and Unregistered IP Address:

 Registered IP Addresses: The IP addresses that the Internet Service Provider provides (ISP) registers as the Domain Name, their recognized IP The address is called Registered IP Address. Approved or registered IP addresses are usually Public Addresses And they are visible on the Internet. Registered IP addresses are networks of customers through ISPs Assigns automatically to computers.

 Unregistered IP Addresses: Persons without IP addresses not recognized by the ISP Ownership is either Private, Unregistered IP Address or Unregistered IP Address It is said. Unapproved IP addresses are used only by the organization's organization, not external They are not disclosed to strangers.
