  3. 3. What is Internet Protocol ? • IP (short for Internet Protocol) specifies the technical format of packets and the addressing scheme for computers to communicate over a network. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. • IP by itself can be compared to something like the 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 messages back and forth for a period of time.

  5. 5. History andVersion of Internet Protocol • Historically, IP was the connectionless datagram service in the original. Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974 at Institute of Electrical and Electronic Engineers (IEEE), the other being the connection-orientedTransmission Control Protocol (TCP).The Internet protocol suite is therefore often referred to as TCP/IP. • The first major version of IP, Internet ProtocolVersion 4 (IPv4), is the dominant protocol of the Internet. Its successor is Internet ProtocolVersion 6 (IPv6) Website : |Twitter : @zakirhusain92 | Fb :
  6. 6. • Other protocol proposals named IPv9 and IPv8 briefly surfaced, but had no affiliation with any international standards body, and have had no support. • On April 1, 1994, the IETF published an April Fool's Day joke about IPv9. Website : |Twitter : @zakirhusain92 | Fb :

  10. 10. What is IPv4 -- Internet ProtocolVersion 4? • IPv4 (Internet ProtocolVersion 4) is the fourth revision of the Internet Protocol (IP) used to identify devices on a network through an addressing system. • IPv4 is the most widely deployed Internet protocol used to connect devices to the Internet. IPv4 uses a 32-bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses). With the growth of the Internet it is expected that the number of unused IPv4 addresses will eventually run out because every device - - including computers, smartphones and game consoles -- that connects to the Internet requires an address.

  11. 11. What is IPv6 -- Internet ProtocolVersion 6? Website : |Twitter : @zakirhusain92 | Fb :
  12. 12. What is IPv6 -- Internet ProtocolVersion 6? • IPv6 (Internet ProtocolVersion 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP) reviewed in the IETF standards committees to replace the current version of IPv4 (Internet Protocol Version 4). • IPv6 is often referred to as the "next generation" Internet standard and has been under development now since the mid-1990s. IPv6 was born out of concern that the demand for IP addresses would exceed the available supply. Website : |Twitter : @zakirhusain92 | Fb :
  13. 13. The Difference Between IPv6 and IPv4 IP Addresses
  14. 14. The Difference Between IPv6 and IPv4 IP Addresses • An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, could be an IP address. • IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf
  15. 15. After IPv6 ,What Next Now ? • While increasing the pool of addresses is one of the most often-talked about benefit of IPv6, there are other important technological changes in IPv6 that will improve the IP protocol: Website : |Twitter : @zakirhusain92 | Fb :
  16. 16. HereWhat Next ? • No more NAT (Network AddressTranslation) - Auto-configuration - No more private address collisions - Better multicast routing - Simpler header format - Simplified, more efficient routing -True quality of service (QoS), also called "flow labeling" - Built-in authentication and privacy support - Flexible options and extensions - Easier administration (say good-bye to DHCP) Website : |Twitter : @zakirhusain92 | Fb :
