IPIP.net File Format Decoder

If available in Hex, the package can be installed by adding ipdb_decoder to your list of dependencies in mix.exs:

def deps do
  [
    {:ipdb_decoder, "~> 0.1.0"}
  ]
end

To prepare lookups in a given database, you need parse first and hold the results for later usage:

iex(1)> {:ok, database} = IPDBDecoder.parse_database_file("/path/to/ipipfree.ipdb")

Using the returned database contents, you could start looking up

iex(2)> IPDBDecoder.lookup(database, "127.0.0.1")
{:ok, %{}}
