Fixed address inside dynamic range

Well putting in a "reserved lease" in the conf file doesn't sound very different from
defining a host.  Is it the mac address administration that is the problem?

I think I sent a message on this last month;  can you:

set the minimum lease time to infinite: 0xffffffff for the pool
where you want reserved leases and also set the infinite-is-reserved 
flag to true.  All leases in that pool will be reserved.

do you want to take a particular lease and set it to reserved?  That's
a straightforward OMAPI program.  

Editing lease files is is temporary workaround stuff when all else fails.  I
never would do that as part of your administrative practices.  You know
the community is pretty far beyond this kind of stuff, I don't know why
people keep suggesting it.
