  2. ip V6

  3. Why ip V6

  4. ip V4 Addressing Ip v4 :: 32-bits :: :: written in dotted decimal :: :: 192.168.1.1 ::

  5. ip V6 Addressing Ip v6 :: 128-bits :: :: written in hexidecimal :: :: 2001:0000:0001:0002:0000:0000:0000:ABCD ::

  6. Simplifying an IPv6 Address :: 2001:0000:0001:0002:0000:0000:0000:ABCD :1: 2001:0:1:2:0:0:0:ABCD True :2: 2001::1:2:0:0:0:ABCD True :3: 2001:0:1:2::ABCD True :4: 2001::1:2::ABCD False

  7. Conventions for Writing IPv6 Prefixes :1: 2000:1234:5678:9ABC:1234:5678:9ABC:1111/64 :2: 2000:1234:5678:9ABC:0000:0000:0000:0000/64 :3: 2000:1234:5678:9ABC::/64 :4: 2000:1234:5678:9A00::/56

  8. Company1 NA-ISPI Assigns 2340:1111:AAAA/48 Assigns 2340:1111/32 ARIN (RIR) Owns 2340::/12 IANA Assigns 2340::/12

  9. Assigning IPv6 Global Unicast Addresses => Like DHCP-V4 =>Track address => Using Multicast (FF00::/8) Stateful DHCP Static config with EUI-64 Static config Stateless autoconfig • Network discovery protocol (NDP) • Perfix and default route • Using EUI-64 • Stateless DHCP( DNS fro ipv6 ) Static config with EUI-64 Stateless autoconfig Static config

  10. EUI-64

  11. EUI-64 sample MAC Address ::: 0034:5678:9ABC interface ID ::: 0234:56FF:FE78:9ABC

  12. stateless autoconfiguration 1:: The host creates a link-local address 2:: It sends an NS (Neighbor Solicitation) message to its link-local address out the interface. 3:: If there is no reply, DAD (Duplicate Address Discovery) declares the address unique. 4:: If the host doesn’t receive an RA (Router Advertisements) , it sends an RS. 5:: A router on the subnet sends an RA, listing its interface prefix. 6:: The host uses that prefix and the interface MAC address to create its IPv6 address

  13. ip V6 Addressing Type unicast anycast Multicast

  14. Unicast Link local unicast Unique Local unicast global unicast

  15. Unique Local unicast 8bits 40 bits 16bits 64 bits ‘FD’ + Global ID + Subnet + Interface ID :: should not be advertised into the Internet ::

  16. Link Local Unicast 10bits 54 bits 64 bits ‘FE80’ + All 0s + Interface ID :: help solve some chicken-and-egg problems ::

  17. What is that ::1/128 ?? Loopback address

  18. Multicast Addresses All IPv6 nodes on the link -------------------------------------FF02::1 All IPv6 routers on the link------------------------------------ FF02::2 DHCP relay agents --------------------------------------------FF02:1:2 DHCP servers -------------------------------------------------FF05::1:3 All NTP servers -----------------------------------------------FF05::101

  19. :: Larger address space :: :: No more need for NAT :: :: Simpler header for increased router efficiency :: :: No more broadcasts :: :: Stateless autoconfiguration :: :: Built-in support for Mobile IP :: :: Built-in support for IPsec security:: :: Easy IP address renumbering:: :: Capability to have multiple addresses per interface :: :: Routers create link-local addresses for use by IGPs :: :::::NOTICE::::: Routers that straddle the IPv4 and IPv6 worlds encapsulate IPv6 traffic inside IPv4 packets !!!
