# ISC DHCP 4.1 Manual Pages - dhclient.leases

# dhclient.leases

## 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 occurrance.

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

## FILES

**DBDIR/dhclient.leases**

## SEE ALSO

dhclient(8), dhcp-options(5), dhclient.conf(5), dhcpd(8), dhcpd.conf(5), RFC2132, RFC2131.
