DHCLIENT.LEASES(5)          BSD File Formats Manual         DHCLIENT.LEASES(5)

NAME
     dhclient.leases -- DHCP client lease database

DESCRIPTION
     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).

FILES
     /var/db/dhclient.leases.<IFNAME>,  Current lease file.
