			==Notes==
			The command "[[dnsmasq]] --help" is ''supposed'' to return a list of valid DHCP sub-options for the "--dhcp-option" option, but it just returns a summary of all the available options as given in detail on the [[dnsmasq manpage]]. This page will be for reconstructing what that list should actually be, based on that page and any other sources found.
			==Options==
			The option numbers are specified in RFC 2132 and subsequent [[request for comment\|RFC]]s.

			Usage:
			* '''command line''':
			** --dhcp-option=<u>number</u>,<u>value</u>
			** --dhcp-option=option:<u>name</u>,<u>value</u>
			* '''[[dnsmasq.conf]]''':
			** dhcp-option=<u>number</u>,<u>value</u>
			** dhcp-option=option:<u>name</u>,<u>value</u>

			* The special address 0.0.0.0 is taken to mean "the address of the machine running dnsmasq".
			* Data types allowed are comma separated dotted-quad IP addresses, a decimal number, colon-separated hex digits and a text string.
