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 style='font-size:11.0pt;line-height:115%'> 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

    1. NIC Card Network Interface Card or simply LAN card.

    2. Router.

    3. Network Storage Device.

    4. Network Printer.

    5. 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.

IPv4 address classes

  • IP addresses are divided into 5 classes ie. A,B,C,D,E

  • Only addresses from class A,B & C are assigned to organization

  • Addresses from class D & E are reserved for special purpose.

  • Address 127.0.0.1 is reserved for loop-back address.

  • If any pc does not have network card then we can install MS LOOP BACK adaptor, and although LAN Card is not present, it act as if there is LAN card.

A

1 126

27 2 = 126

224 - 2 i.e. 16,777,214

255.0.0.0

B

128 - 191

214 -2 = 16,384

216 2 i.e. 65,534

255.255.0.0

C

192 223

221-2= 2,097,150

28 2 i.e. 254

255.255.255.0

D

224 - 239

TCP/IP defines Class D for Multicast address

E

240 255

Reserved for Experiment, Research and Development

 

PRIVATE IPv4 ADDRESS

  • Private addresses can be used if the network is not directly connected to internet

  • The network can connect to internet using proxy server or fire-wall

  • These addresses are used for internal networks.

IPv4 Address can be assigned by following 3 types

1) Static IP Address (Assigned Manually)

2) Dynamic IP Address

3) APIPA Automatic Private IP Address

 

1) STATIC IP ADDRESS:-

Static IP are manually assigned to NIC card by hardware engineer. When you manually assign an IP address, you must manually assign other TCP/IP address options such as subnet mask and default gateway.

2) DYNAMIC IP ADDRESSES:-

Dynamic IP addresses are automatically assigned to computers by DHCP (Dynamic Host Configuration Protocol) server. When a DHCP dynamically assign an IP address, the server also assign subnet mask and default gateway.

3) APIPA Automatic Private IP Address

APIPA are used when a computer is configured for DHCP to assign IP Address, however DHCP server is unavailable for some reason. In this case APIPA will assign IP address in the range from 169.254.0.1 to 169.254.255.254 with the subnet mask of 255.255.0.0.
