  • Conclusions
why lets assume
Why…. Lets Assume
  • IPv6 is needed

What
  • Planning
    • Large project/Small projects
  • Education
    • Technical staff
    • Support staff
    • End users
  • Audit
    • System architecture
    • Yes, No, Don’t know, What?
slide5
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?!?
where

How
  • Address allocation
    • /32, /48, /64, />64, /128
  • Address assignment
    • Stateless auto conf
    • dhcpv6 (Mac OS, XP, 2003 Server )

  • IPv6 enable application
slide9
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
    • …..
