Lease file stay behind until manually removed or overwritten with fresh
leases, so you need to know what's what when parsing them:
$ ls /var/db/dhcpleased/
athn0 cdce0 em0 trunk0 urndis0
For example, there is no cdce0 or urndis0 right now on my box, those are
from past tethering situations and those lease files are useless now.
You can always parse those files but it does not always make sense and
nothing prevents you from dealing with old useless data.
dhcpleasectl on the other hand will check for autoconf set:
$ dhcpleasectl -l athn0
dhcpleasectl: non-autoconf interface athn0
$ dhcpleasectl -l trunk0
trunk0 [Bound]
inet 192.168.0.109 netmask 255.255.255.0
default gateway 192.168.0.1
nameservers 192.168.0.1
lease 1 hours
dhcp server 192.168.0.1

Sure, why not.
