    It's been part of GNU libc for a while, but it has been disabled by
    several distributions. Usually, random selection leads to better
    results. At they very least, it makes renumbering much simpler
    because all addresses are equal, independently of where your clients
    are located.

    It's been a PITA to get this resolved (both in the IETF and in
    implementations), and it's still not done AFAIK.
