DHCP client database of acquired leases
- /var/db/dhclient.leases for DHCPv4
- /var/db/dhclient6.leases for DHCPv6
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 the entry for dhclient.conf.
dhclient was written by Ted Lemon under a contract with Vixie Labs. Funding for this project was provided by Internet Systems Consortium. Information about Internet Systems Consortium can be found at http://www.isc.org.
