CIDR, a Classless Inter-Domain Routing library for Elixir

Setup

To use this library in your project, edit your mix.exs file and add cidr as a dependency:

defp deps do
  [
    {:cidr, ">= 0.2.0"}
  ]
end

Parse an IP address / CIDR:

iex(1)> cidr = "1.2.3.4/24" |> CIDR.parse
%CIDR{ip: {1, 2, 3, 4}, mask: 24}

Match against a CIDR:

iex(2)> cidr |> CIDR.match({1,2,3,100})
true
iex(3)> cidr |> CIDR.match({1,2,4,1})
false
