Description

In some IPv6 environments the need has arisen for hosts to be able to utilise a unique IPv6 prefix even though the link or media may be shared. Typically hosts subscribers) on a shared network, like Wi-Fi or Ethernet, will acquire unique IPv6 addresses from a common IPv6 prefix that is allocated or assigned for use on a specific link. Benefits of a unique IPv6 prefix compared to a unique IPv6 address from the service provider are going from enhanced subscriber management to improved isolation between subscribers. In most deployments today IPv6 address assignment from a single IPv6 prefix on a shared network is done by either using IPv6 stateless address auto-configuration (SLAAC) and/or stateful DHCPv6. While this is still viable and operates as designed there are some large scale environments where this concept introduces significant performance challenges and implications, specifically related to IPv6 router and neighbor discovery. This presentation will provide an overview of how IPv6 community Wi-Fi best common practices documented in draft-ietf-v6ops-unique-ipv6-prefix-per-host.

Summary

This presentation outlines an approach utilising existing IPv6 protocols to allow hosts to be assigned a unique IPv6 prefix (instead of a unique IPv6 address from a shared IPv6 prefix), and will mainly focus around applicability for WiFi access. The presentation will be based around IETF V6OPS Operational Best Common Practice draft-ietf-v6ops-unique-ipv6-prefix-per-host.
