I need that my IP addresses in subnet would not be allocated from the beginning, but it would go to the next IP compared to previous used:

instance1 created: 1.1.1.1

Instance2 created: 1.1.1.2

instance1 deleted.

instance2 deleted.

Instance3 created: 1.1.1.3 (not 1.1.1.1 again)

I remember have read about such, do not remember how to google it...
