IP address: its purpose and mechanism

IP addresses are a great protagonist of the current capabilities of the Internet. But what is an IP address? What is it for? Why do I need to know? Don’t worry, here we tell you everything you need to know about the subject. For understanding an IP address read the entire article carefully;

What is an IP address?

The first thing you need to know is the meaning of meu ip. These are the initials of the Internet Protocol, which can be translated into Spanish and called the Internet Protocol. In other words, it is a standard system in which the Internet functions in the process of sending and receiving information.

An IP address is a unique, non-repeated set of numbers that identify devices that can connect to the Internet, such as computers, tablets, mobile phones, and even smart devices prepared for the Internet of Things (IoT). Imagine that the roads in your city are the Internet, and the vehicles that circulate over it are the devices that people navigate to. Regardless of the means of transportation, they all have license plates, which identify and distinguish them. In this sense, the license plate of the vehicle in this example can be said to be the IP address of the device connected to the Internet.

What is an IP address? 

The IP address is used to identify the device connected to the Internet. It also works to find computers and web portals together on the network.

IP address type

IP can be divided into two types: public and private. It can be used in two ways: dynamic IP and static IP.

Private IP address

This is a set of numbers assigned to each computer connected to your private network. For example, an IP address is generated when you connect your mobile phone, tablet, or computer to your home Wi-Fi network.

Private IP addresses, on the other hand, fall into three sets of numbers. These are:

  • Class A: From to It is typically used for large networks, such as the networks of some multinational corporations.
  • Class B: From 172.16.00 to It is intended for medium-sized networks such as local businesses and schools.
  • Class C: From to Supports small networks such as home networks.

Public IP address

These are visible to everyone who browses the Internet and help identify users on large networks. It targets servers that run 24 hours a day and can hire as many as you need. These are numbers that identify the connection points between devices in your network and the Internet.

How to use the IP address


The IP address assigned to the device will not change. This means that you will use the same IP number for the rest of your life.  Static meuip addresses improve stability and download speed. However, it may be more vulnerable to certain shortcomings, such as hacker attacks. Hackers have more time to manipulate them because they are static addresses.


The dynamic IP address is characterized by being changed each time the device connects to the Internet. It is commonly used when the provider has more clients than the IP address because it is unlikely that they will all connect at the same time.

However, the weakness of this type of IP address is that it occurs more often than static IP and can disrupt the connection. Therefore, it is often necessary to disconnect and connect to the modem that provides Wi-Fi at home in order to improve the connection, that is, to change the IP number.

How does an IP address work?

Now that you have defined what an IP address is, let’s learn how it works. The router is responsible for assigning IPs to the various connected devices. For the same reason, it is not possible to maintain a fixed connection between multiple devices such as shared folders and printers. Each time the computer is connected, the computer’s IP will be different. This is what happens with dynamic IP. Instead, when we talk about static IP, we talk about IP addresses that don’t change, as the name implies. This is only possible by configuring on the device.

What is the relationship between IP addresses and domains and web servers?

Web pages are created with files. These are stored on your computer to convert it into an interface that all users can see on the Internet.

The computer that stores information on a website is a server, which has one or more IP addresses that identify it (for example, “”). Previously, at the beginning of the Internet, computers communicated with each other over IP addresses without using domains or DNS. This is the same way someone calls a friend on a landline and talks. I needed to know the number or save it on some agenda

What is DNS?

DNS (Domain Name System) is responsible for “translating” IP address numbers into domain names. That is, it translates the domain written in the browser and directly accesses the server pointed to by the domain.

Where is the IP address of the server when signing up for web hosting?

Now that you know what an IP address is, its purpose, and its importance in the huge world of the Internet when buying a web hosting plan to host your website, you should keep the following in mind: It is important. Information about the IP address that corresponds to the server that stores the information on the website through the provider. You need to associate it with the registered domain name.
