    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.

    Use IPv6 anycast to findthe DNS server address using

    a reserved address(server has to be declared).

    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.
