Translated by Akira Kato
In a morning, there was an Oracle:

Are you ready for Are you ready for
IPv6 service?IPv6 service?
Introduction
• Only a few years to IPv4 address depletion– Situation is getting serious– It is a matter of time that Ipv4 address
depletion happens.
3
Is the problem only addr depletion?• Such problem has not been shared with
anybody other than L3 people– Too late to start something when IPv4
address space is once depleted
• Only a few providers provide IPv6 service– Especially datacenter operators
• Operational experience on IPv4/v6 co-exisitng environment? – Not only dual-stack is a solution
4
…ということで プロローグ
•小人たちは集まります– Webサービスを提供するホスティング事業者は IPv6に対応できるか?を検討する•何が必要か•何に苦労するのか•ガッカリすることはなんだろう?•小人たちは IPv6にウットリできるんだろうか?

First Bake-off
• Dwarves try it first– Does currently established technology
make IPv6 to follow IPv4's footsteps?•What is the key of network
confiugration?•Does it work at all?
– Any problem in service migration?•Is the migration an easy task?

Design -1st stage-

Additional BB Router
IPv4 test environment
IPv6 test environment
Second Bake-off
• The dwarves tries again– How IPv4/v6 translation works?– Is it possible to monitor IPv4/v6 ?– Make the toplogy more realistic– Communication test from an IPv6 only
client to an IPv4 server – How problems detected in IPv6
environment?

Design -2nd stage-

The dwarves got Level up !
The dwarves got Level up !
The results...
• The second bake-off didn't completed smoothly– Number of dungeons (like blackhomes)
around the clients– Many bugs in server-side– Monsters generated when dual stack
enabled– A cursed spells called “Specification”

Summary• What obtained through expeirments
– Need to deliver the warning to all those woking in the network
• Other thoughts– Decision by the providers could
minimize the damage in the IPv4 address depletion issue.
– Everybody needs to realise the resposibility as a network operator not to impede the network development
16
When you make a decision
• Use it• Get used to it• Bring it up• Train it• Raise the level• Look for customers who pay for it• Create services the customers pay
for

WE CAN DO ! WE CAN WE CAN DO ! WE CAN DO !!DO !!

It is a nice moment to start the IPv6
services
THANK YOU!
