Front-end proxies need to speak IPv6 to the outside world so they can accept connections from IPv6 clients, add the clients' IPv6 addresses to the HTTP X-Forwarded-For header which gets passed to the Apaches, and then return the response body back to the client.
Interesting. Is there a standard for using IPv6 inside X-Forwarded-For headers? I would think you'd need a new header altogether.
(Yes, this is just used internally so it doesn't matter, but I'm still curious.
