Posted on April 12, 2022 by Dave

If you’re searching on the Internet for what IPv4 is, you’ve come to the right place. In this article, we’ll take a look at what its purpose is and what its main advantages and disadvantages are.

IPv4 – definition

IPv4 is the fourth iteration of the Internet Protocol and a widely used protocol for data exchange over various types of networks. In packet-switched layer networks, such as Ethernet, Internet Protocol version 4 is a connectionless protocol. Instead, it establishes a logical connection between network devices by assigning each one a unique identifier. Depending on the type of network, there are a variety of ways to configure IP version 4 with various devices, including manual and automatic configurations.

What is Anycast DNS?

Anycast DNS is a form of communication or routing technology that allows you to send and receive data quickly. One IP address can be entered into several DNS servers around the world using this method. Any of them has the ability to react to the request. The goal is for the server that is nearest to the user in terms of distance to respond. This significantly speeds up the response time.

Dynamic DNS, also commonly called Dyn DNS or DDNS, is a great technology that helps with auto-updating the name servers. Every time when the IP address (IPv4 or IPv6) changes for some reason, that beneficial service is going to refresh the DNS records – A record and AAAA record.

Domain Name System – Definition

The Domain Name System is also frequently called shortly DNS, is a decentralized hierarchical infrastructure. Thanks to it, the Internet is as simple and easy for people as it is nowadays. At its core, it includes a database with all of the existent domain names and the IP addresses associated with them.

When a user wants to visit a particular website, types its domain name. That triggers a long DNS process for finding its IP address (IPv4 or IPv6). The domain name has to be translated because machines don’t communicate with words but only with numbers. After the corresponding IP address of the domain name the user wants to visit is found, the browser is able to connect to the website.

Back in the days when the Domain Name System was not designed yet, it was a little bit more complicated to reach a website. It was necessary for users to type the long and difficult IP address, like 54.123.67.89, rather than a simple domain name, such as domain.com. Imagine what a memory challenge it was! The Domain Name system gave the opportunity for people to interact with the domain names and allowed machines to connect with their comfortable language (IP addresses).
