IP-ADDRESSING and IPV4 tutorials

  • If a device wants to communicate using TCP/IP, it needs an IP address. When a device has an IP address and appropriate software and hardware, it can send and receive IP packets. Its like Mobile number, along with mobile number you need hardware (Mobile phone) and software (Sim card Software) to receive or make phone call.

  • NOTE:-Most people think that their computer has an IP address, but actually NIC [Network Interface Card] i.e. LAN card has an IP address.

  • HOST Host mean any device that have IP address. Most of the times it is referred to computer running some services in network. Any device that can send and receive IP packets is called IP Host.

 

IPV4

  • IPv4 stands for Internet Protocol Version 4.

  • IP address is a unique address to identify a host on a network.

  • IP address is made up of 32 Bits Binary numbers (Base 2). It is called as Binary notation.

  • Instead of using 32 bits Binary address at a time, 32 Bits Binary number is address in to 4 blocks of 8 Bits, called an octet.

  • Each Octet can be converted to a decimal number (Base 10) ranging from 0 to 255 and separated by a dot. It is called Dotted Decimal number.

  • Approximately 232 numbers of addresses can be assigned to roughly 4 Billions Host.

 

Binary System

  • In Computer Science and Mathematics, the Binary System represents numeric value using two symbols, 0 and 1 and base-2.

  • Numbers represented by 0 and 1 is commonly called Binary Numbers.

  • In day to day life we use Decimal Numbers, which includes 10 numbers i.e. (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9). Base for Decimal number is 10.

 

 

Note - IPV4

  • Most people think that their computer has an IP address, but in-fact NIC [Network Interface Card] or simply LAN card is assigned an IP address.

  • IP address can be assigned to

  • NIC Card Network Interface Card or simply LAN card.

  • Router.

  • Network Storage Device.

  • Network Printer.

  • IP Camera.

  • We can assign more than one IP address to one LAN Card.

  • If computer does not have NIC then, we can install MS LOOP BACK adaptor and assign IP address to it. Although NIC is not present, it acts as if there is LAN card.
