VNC by default uses TCP port 5900+ N ,[6][7] where N is the display number (usually :0 for a physical display). Several implementations also start a basic HTTP server on port 5800+ N to provide a VNC viewer as a Java applet, allowing easy connection through any Java-enabled web-browser. Different port assignments can be used as long as both client and server are configured accordingly. A HTML5 VNC client implementation for modern browsers (no plugins required) exists too.[8]
