What
- Vendor support
– Claim v6 support (Hw/Sw)
– Does it actually work
– Tech support
- Follow evolving best practice
- Limited Deployment/Testing
- Deployment/Testing
- Dual Stack
- IPv6 only?!?

Stateless auto conf
dhcpv6 (Mac OS, XP, 2003 Server )
dhcpv6 dns/dhcpv4 interaction
Security/Spoofing
Network Access Control
Public addresses vs 10.x.x.x
- Naming
– DDNS/DNS updates

How
- Basic principles
- Supporting Infrastructure
– Routing
– Load balancers
– DNS
- IPv6 enable network
- IPv6 enable hosts
- IPv6 enable application

How
- Testing
–
–
–
–
–
Test environments required
Every application/Every scenario
v4 only, v6 only, mixed v4/v6
Develop procedures
Develop tools
- Rollout/Backout
– Quick and Easy?
- Training and Documentation
