Oh, and I'm lazy.) I do indeed love it when people break out IPv6 addressing as "there's so many addresses, we'll never ever go through them!" Sure, if they're only used as end-point identifiers.Yeah, at some point v6 IP addresses might be used for something completely different. For example, rather than using a cookie to balance through a load balancer to get back to a server in a "sticky session", maybe you are redirected directly to an IP address on the server that represents your session. The IP address could be provisioned dynamically on the server as required, the user hits the main URL and is "redirected" to the unique IP address representing their session.
There isn't a web farm big enough for that not to still work within a /64. Since a web farm network would be a /64 anyway, this isn't an increase in the consumption of IPv6 addresses.
If you have a 64-bit address, each active session can easily be given its own unique IP. I can see requirements at some point for servers to be able to handle thousands of IP addresses per interface.
Many already can. Owen
