IPv6 Zero-Configuration Networks -
Madrid IPv6 Forum 13-15 March, 2002

Application examplesApplication examples
• Home networking:�For users (the majority!) who do not want to be bothered
by device configuration.• Enterprise:
�Capabilities to put in place quickly and change easily the addressing plan (installation, merge and acquisitions, reorganisations, …).

Why IPv6 zeroWhy IPv6 zero--configurationconfigurationis so important?is so important?

Easy to use,bring IP everywhere
Number of addresses,address autoconf
But we need more!!

IssuesIssues• Simplicity of use means:
�Smart and quite complex network protocols.�Security issues.
• What has to be configured?�Router prefix, Host address, DNS server address, DNS
update, Server localisation.• Can everything be 0configured?
�No, in particular some identity and security parameters.

A local application monitors IP addressand updates DNS securely if it changes.

Topics on studyTopics on study
• Some mechanisms and protocols are still drafts and several options have to be tested.
• Router renumbering.• How to use 0conf and IP mobility together?• Security basics:
� “Configuration” of basic identity and security features to be used to secure the auto configuration process.

ConclusionConclusion
• Zero - configuration networks are strategic:�Make use of the IPv6 auto configuration and related
protocols.�Expand the IPv6 market as they really enable IP new
applications for mass market.
• Solutions are coming soon.
