Developed and integrated a RotatingAddressAllocator for the apple/containerization repository, focusing on efficient management of UInt32 network addresses in containerized environments. The allocator employs a FIFO strategy to maximize address reuse while preventing collisions, supporting scalability and deterministic behavior under high churn. Implementation involved creating the RotatingAddressAllocator class in Swift, integrating it with existing network address allocation logic, and delivering comprehensive unit tests to validate allocation, reuse, boundary conditions, and error handling. This work leveraged skills in concurrency, memory management, and system programming, resulting in a robust solution for address allocation that enhances container networking reliability and maintainability.
