  2. Outline • Why Deploy IPv6 • What • Where • How – Choices • Timescales • Conclusions

  3. Why…. Lets Assume • IPv6 is needed • Internet growth • Maintaining connectivity • IPv6 is a good idea • It’s the best solution • There is a business case • Business need • Money and Time are available

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

  5. 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?!?

  6. Where • Network • Security • DNS • Other Infrastructure • Hosts • Wireless (Eduroam Tier 3) • Edge • Server Core • Public services • Internal services

  7. How • Address allocation • /32, /48, /64, />64, /128 • Address assignment • 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

  8. How • Basic principles • Supporting Infrastructure • Routing • Load balancers • DNS • IPv6 enable network • IPv6 enable hosts • IPv6 enable application

  9. 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 • …..

  10. Timescales • 8/6/2011 “World IPv6 Day” • www.google.com • www.facebook.com • Expected 99.95% unaffected • Planning • Decisions • Deployment • Testing • Completion • Years/Ever?

  11. Conclusions • We can do it • It’ll take time • It’ll cost money • There will be some pain • Education • Many decisions • 20:20 Vision in hindsight • Business case • Sensible today?

  12. Questions Any questions ??? a.matthews@abdn.ac.uk
