Why would we reorder?  This is not a given.  First, if the local network
addresses have a longer matching prefix it is automatically preferred.
Second, even if somebody is in the situation where somebody bad a bad
decision that this is not the case (e.g., always remember a machine can
have more than one IP address) you can overwrite the default preferences
getaddrinfo uses for sorting using /etc/gai.conf.
