InternetAddress class

An internet address.

This object holds an internet address. If this internet address is the result of a DNS lookup, the address also holds the hostname used to make the lookup. An Internet address combined with a port number represents an endpoint to which a socket can connect or a listening socket can bind.

Constructors

InternetAddress(String address)

factory

Creates a new InternetAddress from a numeric address. [...]

Properties

address → String

read-only

The numeric address of the host. For IPv4 addresses this is using the dotted-decimal notation. For IPv6 it is using the hexadecimal representation.

host → String

read-only

The host used to lookup the address. If there is no host associated with the address this returns the numeric address.

isLinkLocal → bool

read-only

Returns true if the InternetAddresss scope is a link-local.

isLoopback → bool

read-only

Returns true if the InternetAddress is a loopback address.

isMulticast → bool

read-only

Returns true if the InternetAddresss scope is multicast.

rawAddress → List<int>

read-only

Get the raw address of this InternetAddress. The result is either a 4 or 16 byte long list. The returned list is a copy, making it possible to change the list without modifying the InternetAddress.

type → InternetAddressType

read-only

The type of the InternetAddress specified what IP protocol.

hashCode → int

read-only, inherited

The hash code for this object. [...]

runtimeType → Type

read-only, inherited

A representation of the runtime type of the object.

Methods

reverse() → Future<InternetAddress>

Perform a reverse dns lookup on the address, creating a new InternetAddress where the host field set to the result.

noSuchMethod(Invocation invocation) → dynamic

inherited

Invoked when a non-existent method or property is accessed. [...]

toString() → String

inherited

Returns a string representation of this object.

Operators

operator ==(dynamic other) → bool

inherited

The equality operator. [...]

Static Properties

ANY_IP_V4 → InternetAddress

@Deprecated("Use anyIPv4 instead"), read-only

ANY_IP_V6 → InternetAddress

@Deprecated("Use anyIPv6 instead"), read-only

anyIPv4 → InternetAddress

read-only

IP version 4 any address. Use this address when listening on all adapters IP addresses using IP version 4 (IPv4).

anyIPv6 → InternetAddress

read-only

IP version 6 any address. Use this address when listening on all adapters IP addresses using IP version 6 (IPv6).

LOOPBACK_IP_V4 → InternetAddress

@Deprecated("Use loopbackIPv4 instead"), read-only

LOOPBACK_IP_V6 → InternetAddress

@Deprecated("Use loopbackIPv6 instead"), read-only

loopbackIPv4 → InternetAddress

read-only

IP version 4 loopback address. Use this address when listening on or connecting to the loopback adapter using IP version 4 (IPv4).

loopbackIPv6 → InternetAddress

read-only

IP version 6 loopback address. Use this address when listening on or connecting to the loopback adapter using IP version 6 (IPv6).

Static Methods

lookup(String host, { InternetAddressType type: InternetAddressType.any }) → Future<List<InternetAddress>>

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.
