	<brief_description>
		Internet protocol (IP) support functions such as DNS resolution.
	</brief_description>
	<description>
		IP contains support functions for the Internet Protocol (IP). TCP/IP support is in different classes (see [StreamPeerTCP] and [TCPServer]). IP provides DNS hostname resolution support, both blocking and threaded.

	<methods>
		<method name="clear_cache">
			<return type="void" />
			<param index="0" name="hostname" type="String" default="&quot;&quot;" />
			<description>
				Removes all of a [param hostname]'s cached references. If no [param hostname] is given, all cached IP addresses are removed.
			</description>
		</method>
		<method name="erase_resolve_item">
			<return type="void" />
			<param index="0" name="id" type="int" />
			<description>
				Removes a given item [param 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="PackedStringArray" />
			<description>
				Returns all the user's current IPv4 and IPv6 addresses as an array.
			</description>
		</method>
		<method name="get_local_interfaces" qualifiers="const">
			<return type="Dictionary[]" />
			<description>
				Returns all network adapters as an array.
				Each adapter is a dictionary of the form:
				[codeblock]
				{
				    "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.
				}
				[/codeblock]
			</description>
		</method>
		<method name="get_resolve_item_address" qualifiers="const">
			<return type="String" />
			<param index="0" name="id" type="int" />
			<description>
				Returns a queued hostname's IP address, given its queue [param 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_addresses" qualifiers="const">
			<return type="Array" />
			<param index="0" name="id" type="int" />
			<description>
				Returns resolved addresses, or an empty array if an error happened or resolution didn't happen yet (see [method get_resolve_item_status]).
			</description>
		</method>
		<method name="get_resolve_item_status" qualifiers="const">
			<return type="int" enum="IP.ResolverStatus" />
			<param index="0" name="id" type="int" />
			<description>
				Returns a queued hostname's status as a [enum ResolverStatus] constant, given its queue [param id].
			</description>
		</method>
		<method name="resolve_hostname" keywords="dns">
			<return type="String" />
			<param index="0" name="host" type="String" />
			<param index="1" name="ip_type" type="int" enum="IP.Type" default="3" />
			<description>
				Returns a given hostname's IPv4 or IPv6 address when resolved (blocking-type method). The address type returned depends on the [enum Type] constant given as [param ip_type].
			</description>
		</method>
		<method name="resolve_hostname_addresses">
			<return type="PackedStringArray" />
			<param index="0" name="host" type="String" />
			<param index="1" name="ip_type" type="int" enum="IP.Type" default="3" />
			<description>
				Resolves a given hostname in a blocking way. Addresses are returned as an [Array] of IPv4 or IPv6 addresses depending on [param ip_type].
			</description>
		</method>
		<method name="resolve_hostname_queue_item">
			<return type="int" />
			<param index="0" name="host" type="String" />
			<param index="1" name="ip_type" type="int" enum="IP.Type" default="3" />
			<description>
				Creates a queue item to resolve a hostname to an IPv4 or IPv6 address depending on the [enum Type] constant given as [param ip_type]. Returns the queue ID if successful, or [constant RESOLVER_INVALID_ID] on error.
			</description>
