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

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 netmask {
host ... {
