socket.remotePort The numeric representation of the remote port. For example, 80 or 21.

socket.resume() Resumes reading after a call to pause().

socket.setEncoding([encoding]) Set the encoding for the socket as a Readable Stream. See stream.setEncoding() for more information.

socket.setNoDelay([noDelay]) Disables the Nagle algorithm. By default TCP connections use the Nagle algorithm, they buffer data before sending it off. Setting true for noDelay will immediately fire off data each time socket.write() is called. noDelay defaults to true. Returns socket.

socket.ref() Opposite of unref, calling ref on a previously unrefd socket will not let the program exit if it's the only socket left (the default behavior). If the socket is refd calling ref again will have no effect. Returns socket.

socket.remoteFamily The string representation of the remote IP family. 'IPv4' or 'IPv6'.

socket.remoteAddress The string representation of the remote IP address. For example, '74.125.127.100' or '2001:4860:a005::68'. Value may be undefined if the socket is destroyed (for example, if the client disconnected).

socket.pause() Pauses the reading of data. That is, 'data' events will not be emitted. Useful to throttle back an upload.

socket.localPort The numeric representation of the local port. For example, 80 or 21.

socket.localAddress The string representation of the local IP address the remote client is connecting on. For example, if you are listening on '0.0.0.0' and the client connects on '192.168.1.1', the value would be '192.168.1.1'.
