2. What is IP?
 IP specifies the format of packets , also called datagram , and the
addressing scheme.
 Most network combine IP with a higher level protocol called
Transmission Control Protocol (TCP) , which establishes a virtual
connection between a destination and a source.
 IP itself is something like a postal system.
 It allows you to address a package and drop it in the system , but
there’s no direct link between you and the recipient.
 TCP/IP , on the other hand , establishes a connection between two
hosts so that they can send message back and forth for a period of
time.

3. Purpose of Internet Protocol.
Need a standard means of communication between
devices
Can’t communicate if speaking two different
languages.
Therefore we have a concept called “Protocol”.
Internet Protocols are set of rules governing
communication within and between computers on a
computer network.

4. Main Function of Internet Protocol
 Identifying errors.
 Compressing the data.
 Deciding how the data is to be sent
 Addressing the data
 Deciding how to announce sent and
received data.

5. Commonly used Internet Protocol
 TCP/IP – The Transmission Control Protocol/Internet Protocol suite
protocol has become the dominant standard for internetworking.
TCP/IP represents a set of public standards that specify how
packets of information are exchanged between computers over
one or more network.
 FTP - File Transfer Protocol provides services for file transfer
and manipulation.FTP allows multiple simultaneous computer that
lacks security features
 HTTP – Hyper Text Transfer Protocol governs how files such as text
, graphics , sounds and video are exchanged on the World Wide
Web(www).

6. IP address
 An IP address is a unique global address for a network
interface.
 It is a 32 bit long identifier
 Encodes a network number( network prefix) and a host
number.

7. IP versions
IPV (1-3) – were not formally assigned.
IPV4 – TCP/IP , 32 bit IP address currently used.
IPV5 – Internet Stream Protocol (SP)
- Experimental Protocol
- Never Introduced for public use
IPV6 – Designed to replace IPV4 , 128 bit IP address

8. Features of IPV4
Connectionless protocol and best effort based.
Familiarity
• Millions of devices are already knowing it
• Existing infrastructure already support it
Simplicity
• It is simpler and easy to remember
• Require less memory

9. Why IPV6?
IPV6 provides a platform on new internet
functionality that will be needed in the immediate
future and provide flexibility for future growth and
expansion.
