# dhclient.leases(5)

DHCP client lease database

## 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)](/dhclient.conf/5.md).**

## FILES
