In Ruby there are a slew of different options for working with IP addresses, including the built in
IPAddr class, but up till now Crystal has been lacking such functionality.
But no more! Subnet is a shard that makes working with IP addresses in Crystal not only possible, but extremely simple. It allows addresses to be used in Range literals, the creation of subnets and supernets, and many other things.
Sorry for bombarding you with projects ;)
