There's no way to do this with the ISC DHCP software distribution as
we release it.

'Nearly' is a more important distinction to me than you seem to

Even if you gave out a random IP address, what makes you think your
customers won't use dynamic DNS to locate their systems?

Randomizing IP address allocations doesn't win you anything, so all
it does is help things break more often and give your customers poor

I strongly advise against this practice.
