Files Used by the DHCP Service

Language:

The following table lists the files that are associated with DHCP.

Table 4 Files and Tables Used by DHCP Daemons and Commands

File or Table Name	Description
`/etc/inet/dhcpd4.conf` `/etc/inet/dhcpd6.conf`	ISC DHCP only: Contains configuration information for the ISC DHCP server, `dhcpd`. For more information, see the `dhcpd.conf` (7) man page.
`/etc/dhcp/interface.dhc` `/etc/dhcp/interface.dh6`	Contains the configuration parameters that are obtained from DHCP for the given network interface. For DHCPv4 the filename ends with `dhc`. For DHCPv6, the filename ends with `dh6`. The client caches the current configuration information in `/etc/dhcp/interface.dhc` when the interface's IP address lease is dropped. For example, if DHCP is used on the `qe0` interface, the `dhcpagent` caches the configuration information in `/etc/dhcp/qe0.dhc`. The next time DHCP starts on the interface, the client requests to use the cached configuration if the lease has not expired. If the DHCP server denies the request, the client begins the standard process for DHCP lease negotiation.
`/etc/default/dhcpagent`	Sets parameter values for the `dhcpagent` client daemon. See the `/etc/default/dhcpagent` file or the `dhcpagent`(1M) man page for information about the parameters.
`/var/db/isc-dhcp/dhcp4.leases` `/var/db/isc-dhcp/dhcp4.leases~` `/var/db/isc-dhcp/dhcp6.leases` `/var/db/isc-dhcp/dhcp6.lease~`	ISC DHCP only: Lists leases for DHCPv4 and DHCPv6 servers. Files with "~" at end of the file name are previous copies.
