Kevin Oberman - Overview
• Exhaustion of IPv4 space and its impact
• Hardware limitations (RIN, FIB, and CPU)
• IPv6 transition (lack of) progress
• IPv6 transition problems– Possible problems made worse by successful transition
– Call for ideas to get there

Michael Sinatra - Campus Transition
• Many problems– Poor dual stack implementations– DNS Issues, especially simple glue records
• Educause did not handle IPv6 addresses correctly• Most registrars don't register IPv6 glue
– DHCPv6 Servers???• No server in Windows• No server in Mac OSX• Almost ready in most Unixen
– DHCPv6 Clients???• Not in Mac OSX (and not coming)• Vista has some issues, but mostly works• Most Linux still MIA• Ubuntu works if the dibbler-client is added• BSDs work
• Even trial jabber server had major problems

Brent Sweeny – BGP Path Hinting
• An update of Brent's proposal to use BGP communities to “hint” to providers about which path is preferred
• Proposal more complete
• More work needed and volunteers to try things are needed

David Meyer – Routeviews
• History and update on routeviews
• Examples of accessing the data and ways it has been used
• Overview of available facilities and archived data
• New capabilities and tools– BGPmon looks especially interesting
• Ongoing issues and problems

Caren Litvanyi – IPv6 on CPS
This was a discussion of the implementation of IPv6 commercial peering.
Very limited (because not may commercial nets do IPv6
Probably not of interest to ESCC

David Meyer – LISP: Keeping the FIB Under Control
• LISP is an encapsulation (jack-up under the network layer)
• Provides locator and end-system ID
• Allows routing based on locators through DFZ
• End-system IDs used only by enterprise and local provider (hopefully)
• Read the papers. This is a complex proposal not easily summarized.
• David is looking for volunteers to try the very green code and see what they think.

Xing Li – IPv6 in China
• The size of this effort is simply on a different scale from what we are looking at
• China has far more IPv6 implementation than most of the world
• Much internal networking is over IPv6
• Done largely by building new nets as opposed to transitioning existing networks

Chris Heermann – Breakable Experimental Network
• BEN is a fiber network that may be used for testing and development and may be broken as needed
• Based out of Research Triangle and connects Duke, UNC and NCSU
• Testing and experimentation can be done at all network layers (1-7)

Where do we go from here?
• We need a viable transition to IPv6 now– See http://www.civil-tongue.net/clusterf/
• Contribute ideas• Prepare to feel Randy's wrath :-)
• Look for ways to limit FIB growth (e.g. LISP)
• Look around for unused address space– Maybe you can sell it to get the budget for
Sup750-3BXL upgrades
• Don't panic! (Note the large, friendly letters)
– The answer is 42
