## NAME
       dhclient.leases - DHCP client lease database

## DESCRIPTION
       The 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)](https://www.chedong.com/phpMan.php/man/dhclient.conf/5/markdown).**
