You just have to look harder :) "The tag system works as follows: For each DHCP request, dnsmasq col‐ lects a set of valid tags from active configuration lines which include set:<tag>, including one from the dhcp-range used to allocate the address, one from any matching dhcp-host (and "known" if a dhcp-host matches) The tag "bootp" is set for BOOTP requests, and a tag whose name is the name of the interface on which the request arrived is also set."
