I don't see why you would need to do that. If a subnet prefix is a /64, that leaves 64 bits for virtual hosts on that subnet, each of which could participate in neighbour discovery. Why do you need structure in the interface ID? (Of course, you could certainly choose to number the virtual hosts consecutively within the IID space, but that's an implementation detail, and might be undesirable for security reasons.)
However - it is clear that massive server virtualisation using global addresses is possible with IPv6. Regards Brian Carpenter University of Auckland On 2007-09-26 08:36, Arul Kumar Chellappan wrote:
Dear All, With virtualization gaining momentum, would there be an option in IPv6 where it has a mechanism to address a virtual host from the real world. Like the 128bit IPv6 address having [Network Prefix][Host ID][Virtual host ID]. For the backward compatibility, the host part could be subdivided into real host ID and the virtual host ID and range of virtual host IDs could represent a single real node. Yes, I understand about the major implementations now have no provitions for that but multicast addressed like ALL_VIRTUAL_NODE_ON_THIS_REAL_NODE that would help in easy management of that device. This is just my initial thought, with limited understanding on virtualization and IPv6. Could you please let me know your thoughts on this.
