IPv4 protocol  What is it and how does it work? + Limitations ▷ 2020

In the case of IP it means Internet protocol, which is used mainly to perform the delivery of datagrams between hosts on a network. This is basically what allows the data can be sent from a computer to another computer over the Internet. This protocol is usually characterized by working at high speed.

Therefore, when we refer to IPv4, we are simply referring to what is the fourth version of the Internet Protocol, which has been adapted and is used on a large scale for data communication between different types of networks. Currently this internet protocol has become one of the most important.

In accordance with all this, here we are going to explain a little more about what the IPv4 Y how it currently works in computer networks. Considering that this is based on packet-switched layer networks, like Ethernet.

What is IPv4 and what is this protocol for in computing?

What is IPv4 and what is this protocol for in computing?

Nowadays IPv4 is the addressing protocol most used in most devices, and this is because internet providers they have not yet decided to go completely to what is the new IPv6 protocol. That way IPv4 has become a fundamental Internet tool, since it allows identify the different computers that are connected to a network.

They also have 32 bits, what allows to offer more than 4.3 billion unique addresses, although the vast majority are already reserved to perform some specific tasks, such as Private IP (LAN) ranges that are not routable over the Internet.

Usually a IPv4 address It is represented under a decimal format that is separated by points, the 32 bits are separated into octets of 8 bits each. Therefore, these addresses are mostly written with 4 decimal numbers that go from 0 to 255. An example of this would be: 172.128.1.2

If a device does not have this address, it cannot be identified on the network, this will not allow you to transfer or receive information with other devices on a public or private network. Usually there is a minimum address that can be 0.0.0.0.0 or a maxim like 255.255.255.255.255.

What are the advantages and limitations of this version of the IP protocol?

The IP protocol or network connections, is a protocol that has a lot of rules that everyone must abide by the software or companies in order that all its products are compatible with each other. Each of the parts of this protocol has the function send emails, transfer data or files, route messages, transfer data using data blocks or packages, among many others.

Then, We are going to introduce you to the main advantages of this tool, as well as its limitations:

Advantage

  • Lower operating costs to Internet providers.
  • It presents a great reliability to users.
  • It’s compatible with standard tools to analyze the operation of different types of networks.
  • It has a lot of Assigned IPs.
  • Used both for large and medium networks.

Disadvantages

  • May be slow in networks have a medium low traffic volume.
  • As usual are more complicated to configure and maintain.

IPv4 vs IPv6 How are they different and which is better?

IPv4 vs IPv6 How are they different and which is better?

All this has created a large number of doubts among users, where most are unaware of the differences between the two. protocols and which of them is the best. Thus, IPv4 and IPv6 are related to the standards of the IP addresses, they have as objective define an IP address.

The number that differentiates one from the other simply refers to the version number, being one of them version 4 and the other version 6. Until now, version 4 is still the most used today because the most providers they have not gone to the new version of the protocol.

Today there are some differences between these two versions despite the fact that both are IP addresses and which we will show you below:

  • IPv4 being an older version no more new IP addresses to assign, while IPv6 being the new version offers new IP addresses for your devices.
  • Version 4 have IP addresses which are with numerical values ​​of 32 bit that are written in the decimal system, While for version 6 they have 128 bit that are written in the hexadecimal system.
  • Total, of space in version 4:294,967,928 addresses.
  • Total, of space in version 6: 340.282.366.920.938.463.463.374.607.431.768.211.456.

Can the version of the IP protocol I use affect my Internet browsing speed?

Can the version of the IP protocol I use affect my Internet browsing speed?

To be able to assure what is the exchange of information on a network where there are millions of connected computers each of these computers must be identified. For this, each of these devices has a IP number or IP address, taking into account that any package that circulates either website, emails, among others contain the computer’s IP address destination.

In general, these addresses are made up of a series of numbers corresponding to a country, a specific domain and the team itself. And it is that when a computer connects to the network it is assigned in a way dynamic a temporary IP address.

The correspondence between IP and the domain name that is stored in computers is usually constantly updated, and these are called DNS or domain name servers. The DNS they are only in charge of translating domain names so that they are easy to remember in the server’s IP address where they are housed the webpages that we constantly seek.

Keep in mind that browsing speed is directly influenced by DNS, for which the most recommended is to choose the most suitable DNS for this. Thus, the IP version that you are using is not directly related to the speed of your internet, this being a factor that will depend more on the DNS you are using.

IPv4 test How can I find out my IPv4 address quickly and easily?
