# lookup method Null safety

Future<List<InternetAddress>> lookup (

1. String host,
2. {InternetAddressType type: InternetAddressType.any}

)

Lookup a host, returning a Future of a list of InternetAddresss. If `type` is InternetAddressType.ANY, it will lookup both IP version 4 (IPv4) and IP version 6 (IPv6) addresses. If `type` is either InternetAddressType.IPv4 or InternetAddressType.IPv6 it will only lookup addresses of the specified type. The order of the list can, and most likely will, change over time.

## Implementation

    external static Future<List<InternetAddress>> lookup(String host,
        {InternetAddressType type = InternetAddressType.any});
