Typically, this protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23, where a Telnet server application (telnetd) is listening. Telnet, however, predates TCP/IP and was originally run over Network Control Program (NCP) protocols.

  • Why is port 8080 used?

    "8080" was chosen since it is "two 80's", and also because it is above the restricted well known service port range (ports 1-1023, see below). Its use in a URL requires an explicit "default port override" to request a web browser to connect to port 8080 rather than the http default of port 80.
  • Is Port 8080 and 80 the same?

    No 80 and 8080 are not the same. In fact ports are used to make connections unique. Port numbers range from 0 to 65535 out of which upto 1024 are called well known ports which are reserved by convention to identify specific service types on a host. 80 is reserved for HTTP.
