Once the was IPv4

How will IPv6 change the world?
Global addressing:
64+64 format: 1.8E+19 networks, units
1E+16 networks, assuming IPv4 efficiency
1 million networks per human
2 networks per sq.ft of Earth (20 per m2)
Plug and play:
IP networking easier than IPX
Efficient mobility:
Simple instant-on ad-hoc networking
Mobile IP, without servers, without dogleg
Peer-to-peerRTP audio example
Need to learn the address “outside the NAT”
Provide that address to peer
Need either NAT-aware application, or application-aware NAT
May need a third party registration server to facilitate finding peers
If IPv6 is so great, how come it is not there yet
Applications
Need upfront investment, stacks, etc.
Similar to Y2K, 32 bit vs. “clean address type”
Network
Need to ramp-up investment
No “push-button” transition
Key Messages
IPv6 direct addressing of all stations enables peer-to-peer, conferencing, auto-configuration, mobility.
Transition to IPv6 akin to Y2K (upgrade all SW to 128-bit addresses)
To help industry move along this path, MSFT released a stack and an SDK for Win2000; MS will continue to iterate this based on industry feedback
