How is this done?

Using a host statement or marking it reserved in the lease file?

If using a host statement with fixed address, the most likely problem is
that the fixed address must be outside any pool or range that you have
set up.

A host statement with a fixed address does not inform the dynamic part
of the server to not use that address, it is a very direct shortcut to
handing out an address. It is up to the operator to keep the two out of
conflict.
