IPv6

  1. 1. Presented by:Michael Dabydeen (@firelinks)
  2. 2. WHY IPV6• The world is running out of Internet Address.• IPv4 has been officially exhausted.• “On 31 January 2011, the last two unreserved IANA /8 address blocks were allocated to APNIC according to RIR request procedures. This left five reserved but unallocated /8 blocks”
  3. 3. INTERNET ADDRESSES??• Unique addressing system to identify each node (endpoint) on the Internet.• Called IP Addresses
  4. 4. CURRENT ADDRESSING SYSTEM(IPV4)• Designed in the 70’s & 80’s• Represented by the Decimal system• Denoted by dot notation Example: 192.168.2.1Represented in Binary as blocks of 8 bits 00000000.00000000.00000000.00000000 8bits x 4 blocks = 32 bits
  5. 5. CURRENT ADDRESSING SYSTEM(IPV4)• Controlled by IANA - Internet Assigned Numbers Authority• 32 bit Internet Addressing System• Maximum Number of Address  2 ^ 32 Address = 4, 294, 967, 296 total Address• Address are further divided by Regions  AFRINIC - African Internet Information Centre  ARIN – American Registry for Internet Numbers  APNIC – Asia-Pacific Network Information Centre  RIPE NCC - Réseaux IP Européens Network Coordination Centre  LACNIC - Latin America and Caribbean Network Information Centre  Guyana Registry
  6. 6. PROBLEM?Internet began exponential growth.In 1996, foresight indicated that the internet will at some point run out of internet address.
  7. 7. SOLUTION?Build a bigger Internet Space ORFind ways to deal with the current one  Subnetting  CIDR Notation  Netmasks  Network Address Translation (NAT)
  8. 8. BETTER SOLUTION?Build a bigger Addressing SpaceInternet Protocol version 6 (IPv6)
  9. 9. ADOPTIONOn June 6th 2011, the world did a test run of IPv6.On June 6th 2012, IPv6 was officially launched, and some of the world top vendors are currently using it.Adoption is slow, but eventually we will all be migrated to IPv6How do you think this will affect us?
  10. 10. ENTER IPV6Larger Address System for Internet Address128 bit Addressing systemBuilt to accommodate 2^128 Addresss or  340,282,366,920,938,463,463,374,607,431,768,211,456 addresses 340 Trillion Trillion  79 trillion trillion more than IPv4  7 billion people on Earth / About 51 Trillion Trillion IP per perso on earth
  11. 11. FEATURES OF IPV6 Stateless Autoconfiguration  Anycast neighbour discovery  Plug and Play Multicast  One to many broadcast
  12. 12. ADDRESSING 16 bit hexadecimal representation Blocks are seperated by colons ( : ) instead of dots . Hex is not case sensitive Zero in an address are almost meaningless and can be replaced by double colons (: : )  2001:0db8:0000:130F:0000:0000:087c:140 B 2001:0db8:0:130F::087c:140B
  13. 13. ADDRESSING CONTINUEDCIDR Still exists Represented in IPv4 192.168.2.1/24 Represented in IPv6 2001:0db8:0:130F::087c:140B /48
  14. 14. IMPORTANT THINGSLoopback Address 127.0.0.1 – IPv4 ::1 or 0:0: 0:0:0:0:0:1 – IPv6Wildcard Address 0.0.0.0 – IPv4 :: or 0:0:0:0:0:0:0:0 – IPv6
  15. 15. CONCLUSION IPv6 address the exhaustion of internet address By providing a larger 128 bit addressing system instead of 32bits Or 3.4 Trillion Trillion Address IPv6 is much improved in quality of IP Addresses IPv6 Address are in hexadecimal  8 Blocks of 16 bits each  Zeros in an IPv6 block is almost negligible IPv6 is currently official and occupies about 1% of the Internet.
