dhclient.leases: DHCP client lease database
dhclient.leases - DHCP client lease database
DESCRIPTIONThe Internet Systems Consortium DHCP client 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. If more than one declaration appears for a given lease, the last one in the file is used. The file is written as a log, so this is not an unusual occurrence.
The format of the lease declarations is described in dhclient.conf(5).
