All was fine until arrived a couple of peripherals that get their IPv4
address via dhcp and there is no way to avoid them to get it, even if you
access then only via IPv6 .
I have added in the imcluded file that assign always the same address to
workstations based on mac addresses record as
host XRX0000AABBCCDD {
hardware ethernet 00:00:aa:bb:cc:dd;
fixed-address 10.240.13.112;
option routers 10.240.13.1;
option subnet-mask 255.255.255.0;
}
but the resut is that while addresse in the "real" subnet assigned to
workstations works fine an are correctly assigned, peripherals insist on
getting public addresses from the pool of portables, that is something i
do not want.
How can i assign completely invalid (or better, unrouted) IPv4 addresses ?

Just to check, do you have a specification for the "invalid" subnet in some
way in the dhcp server pointing in the same direction as the "good" subnet?
It was quite a long time since I messed with dhcp so I may be wrong but I
think that is required for what you want. Like setting an extra (invalid)
address on the same interface and maybe a shared network wrapping with both
of the networks in the dhcp config (no available addresses for the bad one
except the one fixed to the device).
