Ideally I'd scope the subnet to support 4 times the address space required,
for example
Let say you need a /24 subnet, creep the subnet mask back to /22
assign 254 addresses to dhcp server, and 254 to the other and your left
with
2 more sets (possible for future growth, static assignments, etc..)
Assuming its private
address space, its a good idea for each dhcp server to support all the
devices by itself
if need be, without address overlap.. imho..
Thanks,
