The IP adresswhose name comes from the acronym in English internet-protocolis the number that identifies our device on a network.

This number, which acts as a license plate for our device, is a set of four groups of three numbers that follows a logical sequence.

The IP can also be used to access the device or the network remotely.

Differences between public and private IP

If our devices connect to the Internet through our home network, will have two different IPs assignedwhich will identify you in the two different network environments you are connected to, the local network environment and the internet environment.

What is a public IP address?

The public IP identifies our device on the internet.

This IP is assigned to us by our internet provider and normally it varies every time the router is restarted or simply every so often, therefore, if we need to maintain a fixed IP that does not vary, we will have to contact our internet provider.

What is a private IP address?

The private IP It differs from the public IP, in that the private IP is fixed for each device and is not accessible from the internet.

This type of IP is usually used to connect a device (for example a mobile) with an internet connection (for example the Wi-Fi router).

In addition, we can find different ranges of private IPs, being able to find:

Class A range

This type of range is commonly used in large companies that need thousands of connections, this type of range allows 126 different networks and a maximum of 16,777,214 computers connected per network.

This type of range is made up of two blocks, the first block is used for network identification and the other three blocks for device identification (xxx.yyy.yyy.yyy).

Class B range

Rank B is typically used by universities or organizations of a similar size.

Unlike range A we can create a greater number of networks in range B (12,384) but we can have a smaller number of connected devices.

Regarding the composition of the class B range, it is made up of two blocks for network identification and another two for device identification.

Class C range

The class C range is the most common because it is usually used in domestic use.

Unlike range A and B, we will have a greater number of different networks (2,097,152), but with a smaller number of computers (254 per network).

What are IPv4 and IPv6 addresses?

IP addresses IPv4 In a few words, they are the IP addresses that we were talking about before, in this case we have a 32-bit space which allows 4,294,967,296 addresses.

This number of addresses is insufficient for today’s needs, which is why they were born which are longer and more complex than IPv4 addresses, having a space of 128 bits, which translates into 340 sextillion addresses.

Relationship between IP and Domain

In the early years of the internet, the only way to access a website was through the IP address, because domain names such as mydomain.com did not exist.

As the use of the internet and the creation of web pages became more popular, remembering various IP addresses to access a website became an increasingly complicated job.

To solve this, domains were born, and with the help of DNS (Domain name server) we can access a website without having to remember or identify a specific IP address for a website.

Being much easier to remember the name of a domain than an IP address.
