2. Bigger addresses Some bug fixes
What is IPv6
Bigger addresses
Some bug fixes

3. Why – business
Additional service which makes our customers stick with AARNet

4. Why – technical IPv4 address exhaustion predicted for 19 October 2011.
IPv6 is one part of our customer's response.

5. Why now?
Universities take a long time to turn around IPv4 address exhaustion, an iceberg? Want considered adoption, not Y2K-style crisis management

6. IPv6 policy
Going forward, we seek to support IPv6 to the same extent as we support IPv4.
Exceptions require the approval of the CEO.
Rationale: Projects should make the extra effort to implement IPv6 now,
at our own pace, rather than leave AARNet with a overhang of work to
be done in 2010, at the pace of our most demanding customer.

7. Charging
We do not charge for IPv6 traffic
But we will eventually

8. Progress Forwarding  Routing  DNS forwarding  www.aarnet.edu.au 
We offer IPv6 as a IP service, but do not do IPv6 well
for our strategic value-added services.

9. How hard is it? A Hosts work excellently
Windows Xp & Vista, MacOS X, FreeBSD, Linux
B Routers work well
Core forwarding works well
“Features” often don't exist, fewer & different MIBs
NetFlow format change
C Switches work poorly
Link layer bridging obviously works
“Features” don't exist, yet
F Middleboxes often don't work

10. Middleboxes are bad news
Examples
Firewalls
Load sharing and traffic distribution
SSL offload
Rate limiters
Encourage customers not to use these where alternatives exist
Use DNS or OSPF for load sharing
Do SSL offload on PCI cards rather than on an appliance
Exclude IPv6 from rate limiting

11. Activities, 1 of 2 Connecting customers
Most just want part of their campus network connected. This is a reasonable strategy, no need to push for the entire campus, all at once
Training
UQ and AARNet have codeveloped a training course
Industry liason
Sharing AARNet's experiences

12. Activities, 2 of 2 Helping developers and encouraging early adopters
Tunnels from broker.aarnet.edu.au
A cheap way to answer “I need a IPv6 connection”
This needs some work, may outsource that
Real IPv6 at linux.conf.au
We have been approached by major sites to be their IPv6 internet service provider
We are not in that business
But we are willing to peer
And if you are building a link to peer IPv6, then how about IPv4?
