		IP Protocol support functions like DNS resolution.
	</brief_description>

		<method name="clear_cache">
			<return type="void">
			</return>
			<argument index="0" name="hostname" type="String" default="&quot;&quot;">
			</argument>
			<description>
				Removes all of a "hostname"'s cached references. If no "hostname" is given then all cached IP addresses are removed.
			</description>
		</method>
		<method name="erase_resolve_item">
			<return type="void">
			</return>
			<argument index="0" name="id" type="int">
			</argument>
			<description>
				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.
			</description>
		</method>
		<method name="get_local_addresses" qualifiers="const">
			<return type="Array">
			</return>
			<description>
				Returns all of the user's current IPv4 and IPv6 addresses as an array.
			</description>
		</method>
		<method name="get_resolve_item_address" qualifiers="const">
			<return type="String">
			</return>
			<argument index="0" name="id" type="int">
			</argument>
			<description>
				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 [method get_resolve_item_status]).
			</description>
		</method>
		<method name="get_resolve_item_status" qualifiers="const">
			<return type="int" enum="IP.ResolverStatus">
			</return>
			<argument index="0" name="id" type="int">
			</argument>
			<description>
				Returns a queued hostname's status as a RESOLVER_STATUS_* constant, given its queue "id".
			</description>
		</method>
		<method name="resolve_hostname">
			<return type="String">
			</return>
			<argument index="0" name="host" type="String">
			</argument>
			<argument index="1" name="ip_type" type="int" enum="IP.Type" default="3">
			</argument>
			<description>
				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".
			</description>
		</method>
		<method name="resolve_hostname_queue_item">

			<argument index="0" name="host" type="String">
			</argument>
			<argument index="1" name="ip_type" type="int" enum="IP.Type" default="3">
			</argument>
			<description>
				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.
