You have not included any logs so it is difficult to say what the server
is doing. Overlapping dynamic IP ranges with static assignments is
generally
a bad idea but I cannot see it causing the symptoms you described.
It is possible that your clients are, at least under some circumstances,
including a client identifier in their requests. That will over-ride the
MAC
address and cause it to get a dynamic assignment (assuming one is available
of course). The logs should tell you if that is the case.
The other issue I noticed is that some of your ethernet addresses
are not in fact valid hexadecimal.
myhost4 == D6:9R...
myhost5 == 06:BW...
That may just be a submission error.
