cola - CIDR Optimization by Lookup and Assignment
COLA is also the acronym for "Collision On Launch Assessment", an assessment performed before a spacecraft launch to ensure there won't be a collision with another orbiting vehicle.
cola is a service for finding an available CIDR block given a parent CIDR block, a mask (desired block size), and list of already used CIDR blocks.
