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?
In my experience, no, it doesn't. Ie. the main reason I disable it is because my ssh sessions hung after some period of time, so ssh had sockets open, but yet the IPv6 addresses kept rotating out. Disabling it definately made the ssh sessions stable on OSX.
Apple codes to the masses. Average web browser user or mail client won't care, that is all they test against. Not people that leave ssh sessions open for days to weeks at a time.
Since no one else has mentioned it yet, mosh is another solution to this for ssh: https://mosh.mit.edu/
