For example, have you ever wondered what kind of servers these companies use? Here you can get some answers to these interesting topics that go unnoticed by many users.

And, so you have the best mobile and internet rate, first you have to Get to know the guts of data centers that make it possible for you to enjoy a wired connection in your home or office, or through mobile lines wherever you are.

What is an ISP?

Un internet service provider, or ISP, is the company that provides you with Internet access. The company can be private or public. Your ISP is the company that gives you the "connection" so you can connect to the Internet, either through mobile data or wired by telephone line, WiMAX, etc. But for this to be possible, these companies need servers to perform their function. These large machines housed in data centers are unknown to many, but here you can learn a little more about them, where all your network traffic goes through.

Functions of an ISP

There are many devices connected to the Internet in homes and businesses. Phones, laptops, desktops, and other internet-enabled devices connect to the world through that device, and ISPs connect them to the world. This is an example of how do ISPs work when downloading files or opening internet web pages.

1. When you use your laptop at home to access a page on a site like linuxadictos.com, the web browser uses the DNS servers that are configured on the device to translate the domain name of linuxadictos.com to the IP address with which it is associated (178.255.231.116), which is the address it is configured to use. In fact, whether you put the IP in the address bar of the web browser or if you put the domain, the result will be the same. All thanks to the DNS servers that act as a database that relates IP with domain.
2. The IP address is sent from your router to your ISP, which forwards the request to the ISP.
3. At this point, the ISP sends the page to your web browser, allowing you to view the web.

This process occurs rapidly, usually in matter of milliseconds. For it to work, both networks must have a public IP address assigned by an ISP. The same principle applies to sending and receiving other files, such as photos, videos, and documents. Everything that is downloaded or uploaded online is routed through an ISP.

mobile data ISP

In the case of mobile telephony and mobile data lines, they work in a similar way, only in this case satellites are involved, in addition to the servers on Earth in data centers. In this way they allow you to be connected wherever you go, thanks to the coverage they offer with technologies such as 4G or 5G.

What kind of servers does an ISP use?

El ISP server type depends on company and size, since not all are the same. For example, there may be an ISP company with 750 Linux-type servers dedicated to network services, while there may also be as many Windows servers for billing and user management issues. However, this can be very variable as I say. However, it is known that servers with GNU/Linux operating systems are very present in this type of services.

Also, keep in mind that an ISP not only provides Internet service, it can also give you other services such as VOIP, telephone line, etc. All this can also be managed with Linux servers and SQL databases. And, regardless of the type, high reliability is needed so that the service does not go down and all its clients are left without it. Must be high availability machines in any case.

On the other hand, it should be noted that these servers have some fairly advanced network equipment, since they are the ones in charge of routing all incoming and outgoing traffic.
