A Need for IPv6?
 IETF IPv6 WG began in early 90s, to solve addressing growth issues, but
CIDR, NAT,…were developed

 IPv4 32 bit address = 4 billion hosts
~40% of the IPv4 address space is still unused which is different from unallocated The rising of Internet connected device and appliance will eventually deplete the IPv4 address space

 IP is everywhere
Data, voice, audio and video integration is a reality Regional registries apply a strict allocation control

 So, only compelling reason: More IP addresses
