Outline: Background Types of IPv6 Features of IPv6 IPv4 Vs. IPv6 IPv6 Routing IPv6 Address Space conclusion

Background  Definition..  Why IPv6 ?

Types of IPv6 Addresses   Unicast – Address of a single interface – One-to-one delivery to single interface   Multicast – Address of a set of interfaces – One-to-many delivery to all interfaces in the set   Anycast – Address of a set of interfaces – One-to-one-of-many delivery to a single interface in the set that is closest   No more broadcast addresses

Features of IPv6  Larger address space  Stateless address auto-configuration  Multicast  Link-local Address  Network Layer Security  Mobility

IPv4 Vs. IPv6

IPv6 Routing  Open Shortest Path First (OSPF)  Routing Information Protocol (RIP)  Inter Domain Routing Protocol (IDRP)  Intermediate System to Intermediate System Protocol (ISIS) # Additional :  IPv6 Extinction Header (Routing Header)

IPv6 Mobile Routing

IPv6 Address Space 128-bit address space – 2128possible addresses – 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses or (3.4 x 10^38) – 6.65 x 10^23 addresses per square metre of Earth’s surface 128 bits were chosen to allow multiple levels of hierarchy and flexibility in designing hierarchical addressing and routing Typical unicast IPv6 address: – 64 bits for subnet ID, 64 bits for interface ID

Summary   IPv6 is the natural future of the Internet
