Good information, but for the purposes of everyone here is this relevant?
I'd assume we're talking about setting up Linux servers, not MS servers.
According to the article, though, the random ID is generated and used for
all permanent IP addresses. The privacy bit for temporary addresses is only
enabled on the client OS's, not the servers.

I am a bit curious as to what happens with the random ID bit, though. Does
it get regenerated with every change in link state, or just when the system
is booted? With decent uptimes you'd basically have a static IP.

Or, you could just run the one command necessary to put it into a normal
EUI-64 based address. So, regardless, you can still essentially have a
static IP on non-DHCP networks.
