10. Future: IPv6 University Networks
The only solution
China: 74 A-class blocks needed if each one holds an IPv4 address!
THU: 20,000 student net-players who are using Internet in their dormitory!
Tunnel Broker driven transition
- A mandatory IPv6 address for each student
- Mobility support

We Believe
Next generation of the network engineers and scientists of China will come from today’s net players.
Where are they today?
