I pv6 final v 1.0

  1. 1. IPv6 – Implementation and Advantages A.M. Jayasekara N.U. Wickamasinghe W.H.M.S.P.Wijetunge W.G.C.W. Kumara
  2. 2. AimIdentifying methods of IPv6 SAITM - RSEA 2012implementation. 2
  3. 3. Content• What is IP?• IPv4• IPv6 SAITM - RSEA 2012• Methods of IPv6 implementation 3
  4. 4. How many people use Internetevery day ? SAITM - RSEA 2012 4
  5. 5. • That is 2,267,233,742 (2.3 Billion) users worldwide SAITM - RSEA 2012 32.7% of the world population 5
  6. 6. SAITM - RSEA 20126
  7. 7. SAITM - RSEA 2012How to identify these users ? How do we name them? 7
  8. 8. That is where the Internet Protocol SAITM - RSEA 2012(IP) comes in ! 8
  9. 9. Internet Protocol - Definition The principal set of procedures used for transferring data packets between SAITM - RSEA 2012 devices on a network-of-networks using the Internet Protocol Suite. 9
  10. 10. IP• An IP is used to , • Address each device connected to SAITM - RSEA 2012 internet • Regulate data transfer between devices 10
  11. 11. There are two commonly used IP versions atthe moment. IPv4 – Internet Protocol version 4 SAITM - RSEA 2012 IPv6 – Internet Protocol version 6 11
  12. 12. IPv4• Uses 32bit addresses • Which limits the address in to 4,294,967,296 (4.3 billion) addresses SAITM - RSEA 2012• Limited security • No authentication or encryption at IP level• Most commonly used version 12
  13. 13. However, By 2014, expected number ofdevices that are connected to the internetis estimated as 50 Billion.[1] SAITM - RSEA 2012 That is 12 times more than current IPv4 can support. 13[1] Internet Corporation for Assigned Names and Numbers (ICANN)
  14. 14. So what will happen ? Do we find ourselves unable to connect to SAITM - RSEA 2012 the internet via new devices ? The answer – NO! 14
  15. 15. Reason for developing IPv6 is to addressthe IPv4 address exhaustion. SAITM - RSEA 2012 15
  16. 16. IPv6 Designed to overcome limitations of IPv4 SAITM - RSEA 2012• Uses 128bit addresses • 340 Undecilion (3.4x1038) addresses• High security • Data encryption and authentication 16
  17. 17. Features of IPv6 Reduced Increased managementaddress space requirement SAITM - RSEA 2012 Better mobility Security support 17
  18. 18. How do we start using IPv6 ? SAITM - RSEA 2012 18
  19. 19. Methods of IPv6 implementationThere are three main methods ,• Dual-Stack SAITM - RSEA 2012• Translation• Tunneling 19
  20. 20. Dual-Stack• It operates both IPv4 and IPv6 simultaneously on the same SAITM - RSEA 2012 infrastructure 20
  21. 21. Dual-Stack Simple, Some SAITM - RSEA 2012 Uses network minimum vendors and resources servers do not support IPv6 21
  22. 22. Translation• Converting IPv6 traffic into IPv4 traffic for transportation and vice versa SAITM - RSEA 2012• Traffic is not encapsulated, it is directly converted to the destination type• Two main methods are used in translate method 22
  23. 23. Translation Methods• Network Address Translation - Protocol Translation (NAT-PT) SAITM - RSEA 2012 • NAT-PT method configure a translation of an IPv4 address into an IPv6 address and vise versa either statically or dynamically 23
  24. 24. Translation Methods• NAT64 • NAT64 mechanism allows IPv6 hosts to communicate with IPv4 servers SAITM - RSEA 2012 • The IPv6 client embeds the IPv4 address it wishes to communicate with and sends its packets to the resulting address 24
  25. 25. Translation Can deal Not a good SAITM - RSEA 2012 with option when different IPv4 uses types of NAT protocols 25
  26. 26. Tunneling• Transporting IPv6 traffic through an IPv4 network transparently SAITM - RSEA 2012• Few different tunneling methods exists for IPv6 26
  27. 27. Tunneling Methods• Manual IPv6 Tunnels • Manually created IPv6 tunnel is configured between two routers, that each must support both IPv4 and IPv6 SAITM - RSEA 2012• 6to4 Tunnels • It is IPv6 to be tunneled via IPv4 • 6to4 allows for automatic IPv6-to-IPv4 address translation, and treats the underlying IPv4 network as one big Non-Broadcast Multi- 27 Access network
  28. 28. Tunneling Used on top Hardware SAITM - RSEA 2012 of an existing must IPv4 network support both IPv4 & IPv6 28
  29. 29. Are we ready for IPv6 ? SAITM - RSEA 2012 29
  30. 30. IPv6 Readiness• Compatibility with IPv6 networking is a software or firmware issue SAITM - RSEA 2012• The American Registry for Internet Numbers (ARIN) has suggested that all Internet servers to be prepared to serve IPv6-only clients by 2012 30
  31. 31. IPv6 Readiness - Software• Most personal computers running recent operating system versions are IPv6- ready• Most popular applications with network SAITM - RSEA 2012 capabilities are ready, and most others could be easily upgraded with support from the developers• Java applications adhering to Java 1.4 (February 2002) standards have support 31 for IPv6
  32. 32. IPv6 Readiness - Hardware• Low-level equipment like network adapters and network switches may not be affected by the change SAITM - RSEA 2012 • since they transmit link-layer frames without inspecting the contents• Networking devices that obtain IP addresses or perform routing based on IP 32 address do need IPv6 support
  33. 33. SAITM - RSEA 2012Finally what should we do ? 33
  34. 34. Now, as available IPv4 addresses are almost over it is the time for ISPs, large and small companies and universities to start migrating to IPv6. SAITM - RSEA 2012Based on the results of this analysis of theavailable technologies it is rewarding tomigrate from IPv4 to IPv6 based on userrequirements. 34
  35. 35. Thank You SAITM - RSEA 2012 35
