PROGRAM:
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.
Use dhcp_release online using onworks.net services
