I suspect this is OSX implementing IPv6 Privacy Extensions. Where OSX generates a new random IPv6 address, applies it to the interface, and then drops the old IPv6 addresses as they stale out. Sessions in use or not.
Isn't the OS supposed to wait for the last user of the old address to close their socket before dropping it?
No… It just waits for the valid lifetime to expire. Privacy addresses don’t refresh their preferred lifetime and start counting the valid lifetime from preferred expiration IIRC. Owen
