cider

CIDR library for Elixer.

Quick Start

{:ok, whitelist} = Cider.whitelist("192.168.0.1-3, 192.168.2.0/24, ::1")
Cider.whitelisted?("192.168.0.2", whitelist) # true

Cider.optimize!("192.168.0.0/31, 192.168.0.2-3")  |> Cider.to_string
"192.168.0.0/30"```

```elixir
Cider.optimize("192.168.0.0/31, 192.168.0.2-4") |> Cider.to_string
"192.168.0.0-4"```

```elixir
Cider.optimize("192.168.0.0-5, 192.168.0.2-3, 192.168.0.4-255") |> Cider.to_string
"192.168.0.0/24"```

```elixir
Cider.optimize("192.168.0.0-5, 192.168.0.2-3, 192.168.0.4-127") |> Cider.to_string
"192.168.0.0/25"```
