NAME

       dhcp_release - Release a DHCP lease on a the local dnsmasq DHCP server.

SYNOPSIS

       dhcp_release <interface> <address> <MAC address> <client_id>

DESCRIPTION

       A utility which forces the DHCP server running on this machine to release a DHCP lease.

       Send  a  DHCPRELEASE  message via the specified interface to tell the local DHCP server to
       delete a particular lease.

       The interface argument is the interface in which a DHCP request _would_ be received if  it
       was coming from the client, rather than being faked up here.

       The address argument is a dotted-quad IP addresses and mandatory.

       The  MAC  address  is  colon  separated  hex,  and  is mandatory. It may be prefixed by an
       address-type byte followed by -, eg

       10-11:22:33:44:55:66

       but if the address-type byte is missing it is assumed to be 1, the type for ethernet. This
       encoding is the one used in dnsmasq lease files.

       The client-id is optional. If it is "*" then it treated as being missing.

NOTES

       MUST be run as root - will fail otherwise.

LIMITATIONS

       Only usable on IPv4 DHCP leases.
