That makes no sense. According to the above is neither 
in the dynip range nor the last one. .129 would be the very first one 
and .254 the last. Could you please give us a real example of "wrong" ip 
address assignment?

I'm operating a large network on v0.9.11 with almost identical setups 
(also a statip .0/25 subnet with dynip .128/25), have experienced no 
issues to date and in fact have just verified with one of the logfiles 
of a busy site that indeed chilli wraps around correctly.
