The flash.net package contains classes for sending and receiving from the network, such as URL downloading and Flash Remoting.

	Class	Description
	DatagramSocket	The DatagramSocket class enables code to send and receive Universal Datagram Protocol (UDP) packets.
	FileFilter	The FileFilter class is used to indicate what files on the user's system are shown in the file-browsing dialog box that is displayed when the FileReference.browse() method, the FileReferenceList.browse() method is called or a browse method of a File, FileReference, or FileReferenceList object is called.
	FileReference	The FileReference class provides a means to upload and download files between a user's computer and a server.
	FileReferenceList	The FileReferenceList class provides a means to let users select one or more files for uploading.
	GroupSpecifier	The GroupSpecifier class is used to construct the opaque groupspec strings that can be passed to NetStream and NetGroup constructors.
	InterfaceAddress	The InterfaceAddress class reports the properties of a network interface address.
	IPVersion	The IPVersion class defines constants representing the different families of IP addresses.
	LocalConnection	The LocalConnection class lets you create a LocalConnection object that can invoke a method in another LocalConnection object.
	NetConnection	The NetConnection class creates a two-way connection between a client and a server.
	NetGroup	Instances of the NetGroup class represent membership in an RTMFP group.
	NetGroupInfo	The NetGroupInfo class specifies various Quality of Service (QoS) statistics related to a NetGroup object's underlying RTMFP Peer-to-Peer data transport.
	NetGroupReceiveMode	The NetGroupReceiveMode class is an enumeration of constant values used for the receiveMode property of the NetGroup class.
	NetGroupReplicationStrategy	The NetGroupReplicationStrategy class is an enumeration of constant values used in setting the replicationStrategy property of the NetGroup class.
	NetGroupSendMode	The NetGroupSendMode class is an enumeration of constant values used for the sendMode parameter of the NetGroup.sendToNeighbor() method.
	NetGroupSendResult	The NetGroupSendResult class is an enumeration of constant values used for the return value of the Directed Routing methods associated with a NetGroup instance.
	NetStream	The NetStream class opens a one-way streaming channel over a NetConnection.
	NetStreamAppendBytesAction	The NetStreamAppendBytesAction class is an enumeration of the constants you can pass to the NetStream.appendBytesAction() method.
	NetStreamInfo	The NetStreamInfo class specifies the various Quality of Service (QOS) statistics related to a NetStream object and the underlying streaming buffer for audio, video, and data.
	NetStreamMulticastInfo	The NetStreamMulticastInfo class specifies various Quality of Service (QoS) statistics related to a NetStream object's underlying RTMFP Peer-to-Peer and IP Multicast stream transport.
	NetStreamPlayOptions	The NetStreamPlayOptions class specifies the various options that can be passed to the NetStream.play2() method.
	NetStreamPlayTransitions	The NetStreamPlayTransitions class specifies the valid strings that you can use with the NetStreamPlayOptions.transition property.
	NetworkInfo	The NetworkInfo class provides information about the network interfaces on a computer.
	NetworkInterface	The NetworkInterface class describes a network interface.
	ObjectEncoding	The ObjectEncoding class is used in defining serialization settings in classes that serialize objects (such as FileStream, NetStream, NetConnection, SharedObject, and ByteArray) to work with prior versions of ActionScript.
	Responder	The Responder class provides an object that is used in NetConnection.call() to handle return values from the server related to the success or failure of specific operations.
	SecureSocket	The SecureSocket class enables code to make socket connections utilizing the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.
	ServerSocket	The ServerSocket class allows code to act as a server for Transport Control Protocol (TCP) connections.
	SharedObject	The SharedObject class is used to read and store limited amounts of data on a user's computer or on a server.
	SharedObjectFlushStatus	The SharedObjectFlushStatus class provides values for the code returned from a call to the SharedObject.flush() method.
	Socket	The Socket class enables code to establish Transport Control Protocol (TCP) socket connections for sending and receiving binary data.
	URLLoader	The URLLoader class downloads data from a URL as text, binary data, or URL-encoded variables.
	URLLoaderDataFormat	The URLLoaderDataFormat class provides values that specify how downloaded data is received.
	URLRequest	The URLRequest class captures all of the information in a single HTTP request.
	URLRequestDefaults	The URLRequestDefaults class includes static properties that you can set to define default values for the properties of the URLRequest class.
	URLRequestHeader	A URLRequestHeader object encapsulates a single HTTP request header and consists of a name/value pair.
	URLRequestMethod	The URLRequestMethod class provides values that specify whether the URLRequest object should use the POST method or the GET method when sending data to a server.
	URLStream	The URLStream class provides low-level access to downloading URLs.
	URLVariables	The URLVariables class allows you to transfer variables between an application and a server.
	XMLSocket	The XMLSocket class implements client sockets that let the Flash Player or AIR application communicate with a server computer identified by an IP address or domain name.
