	dhcpd is warning you that the host declarations are *inside* the
	subnet declaration but will be treated as if they are *outside*
	the subnet declaration.

	subnet ... {
		host ... { }
		host ... { }
		host ... { }
		host ... { }
	} 

	To remove the warning re-write the dhcpd.conf file to move the
	host declarations outside the subnet declaration.

	subnet ... {
	}
	host ... { }
	host ... { }
	host ... { }
	host ... { }

	Mark
