Removing Port Number From Domain

port number is part of the addressing information used to identify the senders and receivers of messages. Port numbers are most commonly used with TCP/IP connections. Home network routers and computer software work with ports and sometimes allow you to configure port number settings. These port numbers allow different applications on the same computer to share network resources simultaneously. Port numbers can vary from 0 to 65535, so total we can get 65536 ports.

A port number is a way to identify a specific process to which the Internet or other network message is to be forwarded when it arrives at a server For the Transmission Control Protocol and the User Datagram Protocol, a port number is a 16- bit integer that is put in the header appended to a message unit. This port number is passed logically between client and server transport layers and physically between the transport layer and the internet protocol layer and forwarded on.

What is the use of port number then and why it should be removed? The basic reason for removing the Port Number from a domain that Adding a port number to an IP address in a hosts file does not make sense. The host's file is to create a relation between an IP address and one or more host names. So why we need to take actions with port numbers?

Port numbers are processed by network hardware and the software automatically. Casual users of a network do not see them nor need to take any action involving their operation. Individuals can, however, encounter network port numbers in certain situations:

      Network administrators may need to set up Port Forwarding  to allow the port numbers of specific applications to pass through a firewall. On home networks, broadband routers support port forwarding on their configuration screens.

      Network programmers sometimes need to specify port numbers in their code, such as in socket programming.

      Sometimes, a Web site URL will require a specific TCP port number to be included. For example, http://localhost:8080/ uses TCP port 8080 rather than the default port 80. Again, this is usually seen in software development environments than in mainstream usage.

Step by Step process of removing port number from domain :

1.        Configure IIS manager.

2.        Add/Allow permission for default port in Firewall.

3.        Active FTP services

4.        c:\inetpub>>ftproot ( Create a new folder by this name  )

5.        IIS server manager>> add new FTP Website-> FTP name: Default FTP and Physical Path: FTProot Path.
