This check is done at IP up time because this is in no way a once-off
check, it could vary from network to network

That said being in post-down.d is completely braindead and should be
removed from there.

On Ubuntu the network interfaces are bought up in the background so it
doesn't cause any delays I beleive Debian still does this in the
foreground however, perhaps we can affect the timeout value of 'host'?
