dhclient.leasesDHCP client lease database

dhclient(8) keeps a persistent database of leases that it has acquired that are still valid. The database is a free-form ASCII file containing one valid declaration per lease. The file is written as a log, so the last declaration is the most recent lease obtained.

The lease file is named /var/db/dhclient.leases.IFNAME⟩, where "IFNAME" represents the network interface dhclient(8) acquired the lease on. For example, if dhclient(8) is configured for the em0 network device, the lease file will be named /var/db/dhclient.leases.em0,

The format of the lease declarations is described in dhclient.conf(5).

Current lease file.
