Instead of allocating all possible IPs in advance, generate them as needed. A loop will cycle through all possible IPs in sequential order, allocating them as needed and marking them as in use. Once the loop exhausts all IPs, it will wrap back to the beginning. IPs that are already in use will be skipped. When an IP is released, it will be cleared and be available for allocation again. Two decisions went into this design: 1) Minimize memory footprint by only allocating IPs that are actually in use 2) Minimize reuse of released IP addresses to avoid sending traffic to the wrong containers As a side effect, the functions for IP/Mask<->int conversion have been rewritten to never be able to fail in order to reduce the amount of error returns.
