What was Wrong?
Can IPv4 Address Space Last Forever?
- NO!
- We must keep IPv4 address, until we are IPv6 ready
- We must keep IPv4 routing table small, until we are IPv6 ready
- CIDR (Means renumbering with UBA)
- We must ACTIVELY be IPv6 ready, when IPv4 addresses are exhausted and IPv4 routing table is unmanagably large
