Let's say I've got a DHCP server that will serve 10 subnets. 9 of the subnets will be on the "" domain and one will receive no domain from the DHCP server. I set

option domain-name ""

as a global parameter in dhcpd.conf. In the specific subnet that I don't wish to give a domain to I can override the global parameter by specifying a new one in that specific block.

My question, however, is how would I completely negate that global parameter for the subnet, rather than specifying a more specific parameter for that subnet?
