**Inherits:** :ref:`Object<class_Object>`

Internet protocol (IP) support functions such as DNS resolution.

.. rst-class:: classref-introduction-group

Description
-----------

IP contains support functions for the Internet Protocol (IP). TCP/IP support is in different classes (see :ref:`StreamPeerTCP<class_StreamPeerTCP>` and :ref:`TCPServer<class_TCPServer>`). IP provides DNS hostname resolution support, both blocking and threaded.

Method Descriptions
-------------------

.. _class_IP_method_clear_cache:

.. rst-class:: classref-method

|void| **clear_cache**\ (\ hostname\: :ref:`String<class_String>` = ""\ ) :ref:`🔗<class_IP_method_clear_cache>`

Removes all of a ``hostname``'s cached references. If no ``hostname`` is given, all cached IP addresses are removed.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_erase_resolve_item:

.. rst-class:: classref-method

|void| **erase_resolve_item**\ (\ id\: :ref:`int<class_int>`\ ) :ref:`🔗<class_IP_method_erase_resolve_item>`

Removes a given item ``id`` from the queue. This should be used to free a queue after it has completed to enable more queries to happen.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_get_local_addresses:

.. rst-class:: classref-method

:ref:`PackedStringArray<class_PackedStringArray>` **get_local_addresses**\ (\ ) |const| :ref:`🔗<class_IP_method_get_local_addresses>`

Returns all the user's current IPv4 and IPv6 addresses as an array.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_get_local_interfaces:

.. rst-class:: classref-method

:ref:`Array<class_Array>`\[:ref:`Dictionary<class_Dictionary>`\] **get_local_interfaces**\ (\ ) |const| :ref:`🔗<class_IP_method_get_local_interfaces>`

Returns all network adapters as an array.

Each adapter is a dictionary of the form:

::

    {
        "index": "1", # Interface index.
        "name": "eth0", # Interface name.
        "friendly": "Ethernet One", # A friendly name (might be empty).
        "addresses": ["192.168.1.101"], # An array of IP addresses associated to this interface.
    }

.. rst-class:: classref-item-separator

----

.. _class_IP_method_get_resolve_item_address:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_resolve_item_address**\ (\ id\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_IP_method_get_resolve_item_address>`

Returns a queued hostname's IP address, given its queue ``id``. Returns an empty string on error or if resolution hasn't happened yet (see :ref:`get_resolve_item_status<class_IP_method_get_resolve_item_status>`).

.. rst-class:: classref-item-separator

----

.. _class_IP_method_get_resolve_item_addresses:

:ref:`Array<class_Array>` **get_resolve_item_addresses**\ (\ id\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_IP_method_get_resolve_item_addresses>`

Returns resolved addresses, or an empty array if an error happened or resolution didn't happen yet (see :ref:`get_resolve_item_status<class_IP_method_get_resolve_item_status>`).

.. rst-class:: classref-item-separator

----

.. _class_IP_method_get_resolve_item_status:

.. rst-class:: classref-method

:ref:`ResolverStatus<enum_IP_ResolverStatus>` **get_resolve_item_status**\ (\ id\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_IP_method_get_resolve_item_status>`

Returns a queued hostname's status as a :ref:`ResolverStatus<enum_IP_ResolverStatus>` constant, given its queue ``id``.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_resolve_hostname:

.. rst-class:: classref-method

:ref:`String<class_String>` **resolve_hostname**\ (\ host\: :ref:`String<class_String>`, ip_type\: :ref:`Type<enum_IP_Type>` = 3\ ) :ref:`🔗<class_IP_method_resolve_hostname>`

Returns a given hostname's IPv4 or IPv6 address when resolved (blocking-type method). The address type returned depends on the :ref:`Type<enum_IP_Type>` constant given as ``ip_type``.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_resolve_hostname_addresses:

.. rst-class:: classref-method

:ref:`PackedStringArray<class_PackedStringArray>` **resolve_hostname_addresses**\ (\ host\: :ref:`String<class_String>`, ip_type\: :ref:`Type<enum_IP_Type>` = 3\ ) :ref:`🔗<class_IP_method_resolve_hostname_addresses>`

Resolves a given hostname in a blocking way. Addresses are returned as an :ref:`Array<class_Array>` of IPv4 or IPv6 addresses depending on ``ip_type``.

.. rst-class:: classref-item-separator

----

.. _class_IP_method_resolve_hostname_queue_item:

.. rst-class:: classref-method

:ref:`int<class_int>` **resolve_hostname_queue_item**\ (\ host\: :ref:`String<class_String>`, ip_type\: :ref:`Type<enum_IP_Type>` = 3\ ) :ref:`🔗<class_IP_method_resolve_hostname_queue_item>`

Creates a queue item to resolve a hostname to an IPv4 or IPv6 address depending on the :ref:`Type<enum_IP_Type>` constant given as ``ip_type``. Returns the queue ID if successful, or :ref:`RESOLVER_INVALID_ID<class_IP_constant_RESOLVER_INVALID_ID>` on error.
