Not necessary.  leave the host statements outside of the scope of any subnet
and they will receive the options from the subnet they are attached to.

SECURITY. You may get an illusion of security, but there really is NO
security in dhcp - it CANNOT prevent someone simply copying the network
settings from another device and using them. My problem is that I don't know
how to change the association of mac-ip from dhcpd.conf file automatically
not by hand (using some match and if statements), based on giaddr (the IP of
the first entry router). You do not need match statements etc, it is handled
automagically by the dhcp server. Simply define multiple IP addresses for
theclient, eg : host pc1 { hardware ethernet aa:bb:cc:dd:ee:ff ; fixed
address 192.168.1.17, 192.168.57.21, 172.20.15.93 ; }
