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?
Bowser talks to server with temp address 1. Sockets close. New temp address generated. User click submit. New temp address used. It is stupid web site design to assume that addresses will be stable even within a session.
