ISC DHCPD giving out reserved IPs for non-reserved hosts

It's a configuration/implementation issue - it's nothing to do with the
standards or RFCs. I think there is some confusion over terminology
here.
In ISC dhcpd you specify a range of dynamically allocatable IP
addresses using the 'range' command. You specify fixed addresses using
the 'fixed-address' command within a 'host' statement.
You must ensure that your range does not overlap or contain any
fixed-address addresses. So this leads to things like:
subnet 1.2.3.0 netmask 255.255.255.0 {
range 1.2.3.4 1.2.3.20;
range 1.2.3.22 1.2.3.100;
...
}
host ... {
fixed-address 1.2.3.21;
...
}
