Figure 3: Web server (blue) and additional content servers (yellow)
So we have another 5 series of separate DNS resolutions, each resulting in multiple name-
servers being contacted.
To conclude, to display just the home-page of “stupid.domain.name” the client have been
in contact with 6 content-servers, and one name-server, which in turn have had

12. Why IPv6 is important?
• Anyone can address anyone else
• Market economy forces should do selection of services
• Innovation is important regardless of location in network
• Future Internet is (again) p2p communication
• For a few years, majority has been client - server
• End to end is important for transformation of society
• For a few years, majority has been client - server

13. What is Swedish Government doing?
• Requested e-Delegation to make a plan
• http://www.edelegationen.se/sida/vagledning-for-inforande-av-ipv6
• Push for A Digital Agenda for Sweden
• Digital divide is of concern
• Everyone should participate
• Transformation of society
• Requested PTS to take one step further
• Describe more in detail what people should do

14. The IPv6 plan
• Vad vill uppnås med denna vägledning?
• Mål: En övergång till IPv6, för myndighetens externa kommunikation
(webbplats och publika e-tjänster), bör vara genomförd senast vid
utgången av 2011. Det är sedan upp till var myndighet att göra sin egna
bedömning av tidpunkten för omställningen av den interna IT-miljön till
IPv6.
• Syfte: Att stödja offentlig förvaltning att i ett första steg genomföra
en konsekvens- analys avseende övergång till IPv6 och därefter
genomföra själva övergången.

26. Why is IPv6 important?
• Services must work over IPv6 when first end user only
have IPv6
• Office network have same environment as end users
• By being first customer, public sector help deployment
of new technologies
