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

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

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

.. _class_IP_method_clear_cache:

- void **clear_cache** **(** :ref:`String<class_String>` hostname="" **)**

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

.. _class_IP_method_erase_resolve_item:

- void **erase_resolve_item** **(** :ref:`int<class_int>` id **)**

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.

.. _class_IP_method_get_local_addresses:

- :ref:`Array<class_Array>` **get_local_addresses** **(** **)** const

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

.. _class_IP_method_get_resolve_item_address:

- :ref:`String<class_String>` **get_resolve_item_address** **(** :ref:`int<class_int>` id **)** const

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>`).

.. _class_IP_method_get_resolve_item_status:

- :ref:`ResolverStatus<enum_IP_ResolverStatus>` **get_resolve_item_status** **(** :ref:`int<class_int>` id **)** const

Returns a queued hostname's status as a RESOLVER_STATUS\_\* constant, given its queue "id".

.. _class_IP_method_resolve_hostname:

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

Returns a given hostname's IPv4 or IPv6 address when resolved (blocking-type method). The address type returned depends on the TYPE\_\* constant given as "ip_type".

.. _class_IP_method_resolve_hostname_queue_item:

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

Creates a queue item to resolve a hostname to an IPv4 or IPv6 address depending on the TYPE\_\* constant given as "ip_type". Returns the queue ID if successful, or RESOLVER_INVALID_ID on error.
