Broadband, or high-speed, Internet connection is what a heap of users presently use in their home. Along with high-speed Internet, numerous users may also use a router to grant multiple computers to connect to the Internet. This post will describe how a router is employed to connect multiple computers. To make it requiring little effort to understand, I will use where you live as a comparison to how your computer is connected to the Internet. What is an IP Address? IP addresses are a series of numbers in the form: nnn.nnn.nnn.nnn, where nnn is a one to three digit number. An IP address is distinguishable to an person computer on a network, similar to how your home has a distinctive address. For an Internet connection, an IP address is supplied by your Internet Service Provider (ISP). In a heap of cases, your ISP may provide you with more than one IP address, which allows you to connect multiple computers. As you will see later, however, you may still connect multiple computers with a single IP address. Connecting a Single Computer Connecting a single computer to your high-speed Internet is very simple to do. Simply connect a network cable into your modem, and then into the network card in your computer. Your computer will then be assigned an IP address from your ISP. For example, if your ISP assigned you the IP address of 24.24.50.17, then your computer will have that IP address. When you make a request to a server, such as for a Web page, the Web server knows which IP address made the request. The selective information is then sent through the Internet and back to your computer. This is similar to when somebody sends you mail to your home. The address on the mail allows it to be delivered to your home and not someplace else. Connecting Multiple Computers How may multiple computers connect if only one address is assigned? When you make a request for a Web page, how does it know which computer requested that page? Let’s take our home analogy one step further. Let’s say rather of living in a house, you live in an apartment. When someone sends you mail, they not only include your address but likewise an apartment number. This number is internal to your apartment building and each apartment has it is own distinctive number. Similarly, multiple computers may connect to the Internet if they each had there own distinguishable local IP address. This may be handled by a router. A router is a piece of hardware that connects directly to the modem. Each computer is then connected to the router, rather of the modem. Now rather of your computer having the IP address supplied by your ISP, your router now is assigned that IP address. This is similar to your router acting as the apartment building. The beauty of a router is that it may assign it is own local IP addresses. When you connect a computer to the router it now receives one of the IP addresses assigned by your router, similar to how each apartment has it’s own number. Now when you make a request for a Web page, the request is sent using the same ISP address, but this time it is assigned to the router. When the Web page is returned, the router receives the request, and sends it locally to the computer that requested the page. The router also has it is own local address that is similar to the local IP addresses of the computers. So now the router has two addresses assigned to it: an external one provided by your ISP, and a local one provided by it. This allows the router to connect to both the Internet and the local network. Note: The 192.168.xxx.xxx address are particular IP addresses reserved for Local Area Networks (LANs). Managing a FTP or Web Server on Your Network Let’s take a look at this scenario. You have a router connecting multiple computers to the Internet. But now you want to construct a FTP or Web server. No problem. You setup the necessary software on a computer on your network, told somebody outside your network the local IP address of your FTP server and they undertake to connect. They then discover that they can’t connect. Why? Its similar to somebody mailing something to you by just specifying your apartment number and no address. The IP address assigned to your computer is local to your network. You may connect to that computer from within your network, but not from the Internet. You will need to use your ISP-assigned IP address (the one assigned to your router) to have an individual from the Internet connect to your FTP server. The problem is that your router is assigned that IP and not your computer, and since an IP address must be unique, how may two computers have the same IP? The answer: they can’t, but they don’t need to. Routers have the capacity to forward data on a port to a specific computer. A port is a numbered channel that info may be sent through on a network. You cannot physically see it as it is a virtual channel employed extensive in networking for sending/receiving data. For FTP servers the default port is 21; notwithstanding another port may be used. Open your router setup and look for the port forwarding option. Specify the internal IP address of your FTP server and the port number and then save that information. Now when a user tries to access your FTP site, they ought to use the ISP IP address that is assigned to your router. The router will then detect that the selective information is being sent on port 21 and then forward it mechanically to your FTP server. A Web server may be setup the same way, but it is default port is commonly 80. Note: By default a router will dynamically assign IP addresses to the computers connected to it. This means that the basi computer to connect to the router will get the introductory available IP address, and the next will get the second, and so on. If you manage an FTP server, it may be requiring little effort to assign a static IP address to the computers to ascertain that the FTP server always has the same IP address. This article described how to connect one or more computers to one Internet connection. It is indispensable to do not forget the following:
