Internet Protocol IP  What is it? + Operation ▷ 2020

The IP address is used daily by us, just by connecting to the Internet. Its functions are many, knowing what it is is very important since it will allow us to configure it, as we need or to connect more devices to it.

There are different types of IP addressesAlthough they all appear to behave the same, in reality they do not. Today we will explain what these types of protocols are and what they are for.

In the last section of this wonderful post, we will show you the steps you must follow to find out what version of the IP protocol you are using. You will find the steps to know the information from your Android or from your Windows.

What is the Internet protocol and what is it for when browsing the web?

The key for a network to work, are the Internet protocols. These are necessary so that what we know as the data exchange between two or more servers / computers. The protocols establish rules and the conditions in which information transfers must be carried out.

In the world of the Internet there are various protocols, but the most common, important and considered as pillars are: Transmission Control Protocol (TCP) and the Internet Protocol (IP).

A little history

What is Transmission Control Protocol (TCP) and what is it for on the Internet?

One of the first civil organizations, which was very recognized and financed even by the Pentagon, formed mainly by Hackers and Researcher Bob Taylor, was ARPA (Advance Research Projects Agency), whose largest project in the 60s, which served as the basis for the promotion of internet protocols, it was the interconnection of computers from different universities, managing to do so through a central server. From this ARPAnet was born.

Then in the 70s DARPA (US Defense Projects Research Agency) was born, where studies on data transmission were carried out, the objective of which was to use satellites together with radio waves, to propagate information.

By the year 75 the first official tests were carried out, and at the beginning of 1982 the TCP / IP became the standard to make the transmission of information through US military networks more effective. In the year 1983 the protocols were activated and officially recognized throughout the country.

So we must understand why many of the people say that the father of communication and internet protocols it was the American army.

How does the IP protocol work in global web browsing?

IP codes identify our computer and our connection, these are transmitted from a router or device through a range that it already has assigned, in other words the IP is our identity, where an emission point and a reception point are established, others usually call it EMIREC, where the reception point changes to be an emitter and the emitter to a receiver.

The main function of IP protocols is to prevent confusion between teams, so there are two types of IP, which are: dynamics and statics. Static is what is assigned to the main device (the one that allows the transfer) while dynamic is assigned to each device, so if we have two or more devices on the same network, each of these will have a dynamic IP different to avoid confusion between them.

Some providers configure the static IP address, although there are many devices where we will have to determine it ourselves. This is because if we do not have a static IP address we will not be able to access the sharing of information.

The same thing usually happens on the Internet, when we connect, an IP address is generated that identifies us, in this way, many of the pages keep a record of the different people or computers that visited it. For this to exist, the colon must share their IPs.

IP Versions What are IPv4 and IPv6 and how are they different?

The more the cyber population grows the greater the demand for data transfer, at first many networks have used the standard protocol known as IP version 4 (IPv4) which offers four-byte (32-bit) long IP addresses, but thanks to the new studies it has been promoted for a few years, the IP protocol version 6 (IPv6) whose length is 16 bytes (128 bits).


Whose foundation or argument for such an impulse is that version 4 of the IP is no longer sufficient, Since devices connected to the Internet have grown a lot, and they need a channel that offers greater data transfer.

There is no Protocol version 5?

The truth is that at the moment this version has not been officially available, however after version 4, the development of the IPv5 protocol was implemented, although its real name was Internet Stream Protocol (ST), but due to transmission errors, it was abandoned before becoming standard.

What are internet protocol IP addresses and what are they for?

IP protocols have as main function the exchange of messages. These messages can carry any information from us, as requested by the recipient, these are often called packages and professionally as datagrams.

They may have different names but in simple terms they refer to the same, because each IP datagram includes both a header, where you specify the origin, destination and other information, as well as the message data itself.

This type of protocol is used by many other higher-level protocols, such as TCP and UDP, as well as all Internet software applications, web browsers, FTP clients, and email programs that use this protocol (IP) as a base.

One of the biggest competition in its time for IP were the IPX / SPX protocols used by Novell NetWare, these were designed to offer very IP-like services. But in spite of everything, due to the fall of NetWare as an operating system, the IPX / SPX protocol was forgotten.

What are the types of IP address in a computer network?

IP addresses are grouped into two types, one Public and one Private, then we are going to show you what are the characteristics of one and the other:

Public IP Address

When we talk about public IP address, we mean all those directions that are visible from all over the Internet and that can be used to identify ourselves as users of this great network. These are assigned to the servers that are active 24 hours and we can hire all that we need.

They are usually provided by the router or modem, so that it serves to create a private network. To add a little bit, these are the number that identifies each interface of the devices within a network specifically, and an Internet connection point.

The public IP address can be divided into two subtypes, such as Fixed or Dynamic IPs. Fixed IPs, are those that the device (modem) emits and that never change, These can be domestic or business.

Which is characterized by offering:

  • Greater speed in uploading and downloading data.
  • A more reliable connection
  • Higher cost, but worth it, for what it offers.
  • Great control over IP addresses, because no one else will be able to use them.

Note: The bad thing about this IP is that must have a good security system since they are more vulnerable to any attack.

Instead dynamic IP addresses, remain in constant change, so it tries to maintain stability in the devices. Whose characteristics are:

  • More security than fixed ones.
  • Connection a bit variant, in terms of speed.
  • They make it difficult to track the Internet.

Private IP Address

On the other hand, private IP addresses are the number that identifies each device within the network, usually most devices share the same public IP.

Private IP addresses can be divided into three subtypes:

  • A class: Which are used for large networks, to
  • Class B: Whose use is mostly for SMEs or study centers, to
  • Class C: Used for small places, such as a home or small business, to

Steps to find my IP address on all my devices fast and easy

Knowing that the IP is the identifier of our computer or network, it never hurts to know what it is. So that here we will show you several methods to be able to know the IP address of your network and that of the device. Follow the list that we provide you:

From a website

What is my ip

This is the simplest method since just by visiting a web page that offers us the opportunity to know what our IP is, we can do it, and the best thing is that the method is quite fast.

Take a look at the step by step:

  • Step 1: First we enter or also to
  • Step 2: In both cases, as soon as the page loads, it will give us all the information from our IP and whether or not we are using Proxy.


With Windows

This method is simple, but it only works for Windows users:

  • Step 1: We go to the network icon or to the option “Setting”.
  • Step 2: Then we look for the option “Network and Internet”
  • Step 3: We are going to “The network properties”, or we simply look for the option “State”.
  • Step 4: It will look like a box, which we click on “Details”. There we find a list of all the selected network information.

connection status

network details

On Android.

Finally we leave you this method, which shows you how to find out what the IP is through an Android. To do this we follow the following steps:

  • Step 1: We are going to “Settings or Configuration”
  • Step 2: There, we look for the option “About device or About phone”
  • Step 3: We are going to “State” and the phone IP address, besides that we can also see the IMEI number and the MAC address of the Wifi.
