What should you be aware of when IPv6 support is starting?

Francesco Prelz

INFN, sezione di Milano

and members of the HEPix IPv6 group.

Summary

  1. What you should be aware of depends on who you are:
    • Network admin (e.g. providing wireless connectivity in this room)
    • Active in management
    • System admin
    • Developer
    • Security Officer
    • End user
  2. The steps to be taken are (by and large) known. Some proud explorers opened the way.
  3. Some lead time is likely needed to prepare for the transition, but how much?
  4. If you are still wondering why we have to do this, remember there's no Plan B.

The IPv4→IPv6 transition.

To-dos for security officers.

To-dos for network admins.

Network equipment supported features.

  • Time may be
    our ally here,
    but the support

Conclusions

Keeping eyeballs happy!

Not the end of the world. Times are ripe...
