Jun 2000) 700+ Million web pages 10k+ ISPs worldwide (5k+ in U.S.); numerous new services Traffic growth 100-1000%/year reported 700 M - 1000 M users by 2002 100 IP Adds/person! Telscom Why do we need IPv6 5 IPv6 Features IPv6 has been recognised as the future protocol by IETF, Eurescom, and 3GPP and vendors

Uses 128 bit address space and Hierarchical addressing Improved routing based on aggregated addresses Autoconfiguration Computers assign themselves an Ipv6 address IP Mobility End devices can roam onto other networks Improved security Authentication and encryption at the packet level Better support for QoS Integrated QoS, multicasting Telscom Why do we need IPv6 6 IPv4 vs IPv6 IPv4

Applications are important for pushing IPv6 it has to be transparent to the end user Interoperability with IPv4 has a cost 100% interoperability is not always necessary We need a credible transition story.
