In a morning, there was an Oracle:

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.

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

…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?

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?

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

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
