INGI research meeting

Shim6 is a multihoming protocol that has been designed by the IETF to suit the requirements of the new version of IP, IPv6. Currently BGP is used to provide multihomed connectivity to sites, but this technique is already now responsible for part of the growth of the BGP routing tables, and it could be even worth with the very long IPv6 addresses. This presentation explains the motivations that led to the design of Shim6, and goes through its functional and security challenges. We conclude with some open research areas.

This paper introduce a "new" allocation scheme for address block that is growth-based. It uses growth rate information of customers for optimizing the allocation. An evaluation is made on historical date from APNIC and China.

LinShim6 0.8 released

Tue, 07/15/2008 - 15:43 by Sébastien Barré • Categories:

LinShim6 0.8 has been released.

LinShim6 is an implementation of the Shim6 protocol, that provides host-centric multihoming capabilities to IPv6.
The major new feature present in version 0.8 is the support for locator updates, that is, the peer is now informed when new locators become locally available.

IPv6 and DNS

By ISC. (authors of BIND)
Nothing really interesting for us.

- It seems that Apple airport Gateway implements full IPv6 (by tunnel?)
- NAT v4->v6->v4 an issue ? It is temporary and an incentive for full IPv6... and it's not worth than v4->v4->v4
