Whilst the host statement is matched at a global level, aren't
attributes such as lease time values inherited based upon syntactic
scope rather than address/netblock matching rules?

We have generated configs which use host statements inside subnet
scopes, knowing full well that the host statements are matched globally
but wanting to be able to inherit values based upon which relay server
sent data to us.

If ISC's dhcpd is inheriting values based upon address matching, then
can someone please state if this has always been the case and, if not,
which version introduced it?
