lookup method
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});
