		DTLS packet peer.
	</brief_description>
	<description>
		This class represents a DTLS peer connection. It can be used to connect to a DTLS server, and is returned by [method DTLSServer.take_connection].
		[b]Note:[/b] When exporting to Android, make sure to enable the [code]INTERNET[/code] permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.
		[b]Warning:[/b] TLS certificate revocation and certificate pinning are currently not supported. Revoked certificates are accepted as long as they are otherwise valid. If this is a concern, you may want to use automatically managed certificates with a short validity period.

			<description>
				Connects a [param packet_peer] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). You can optionally specify the [param client_options] to be used while verifying the TLS connections. See [method TLSOptions.client] and [method TLSOptions.client_unsafe].

		</method>
		<method name="disconnect_from_peer">
			<return type="void" />
			<description>
				Disconnects this peer, terminating the DTLS session.
			</description>
		</method>
		<method name="get_status" qualifiers="const">
			<return type="int" enum="PacketPeerDTLS.Status" />
			<description>
				Returns the status of the connection. See [enum Status] for values.
			</description>
		</method>
		<method name="poll">
			<return type="void" />
			<description>
				Poll the connection to check for incoming packets. Call this frequently to update the status and keep the connection working.
