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

dhclient(8) was written by Ted Lemon under a contract with Vixie Labs. Funding for this project was provided by Internet Systems Consor- tium. Information about Internet Systems Consortium can be found at https://www.isc.org. dhclient.leases(5)
