Recursive DNS Server – Definition & Details

By on Tuesday, October 1, 2024

A recursive DNS server is a critical component in the Domain Name System (DNS) infrastructure, responsible for translating domain names into their corresponding IP addresses. Every time you type a URL, like www.example.com, into your browser, this DNS server works behind the scenes to retrieve the correct IP address that allows you to access the website. In this article, we’ll dive into this topic and explain more about it. So, let our journey begin!

What is a Recursive DNS Server?

A recursive DNS server, also known as a recursive resolver, acts as an intermediary between a user’s device and the authoritative DNS servers. Its primary role is to perform the DNS lookup process on behalf of the user by querying multiple DNS servers until it finds the IP address associated with the requested domain name. This process is crucial for translating human-readable domain names into machine-readable IP addresses, ensuring smooth internet navigation.

What is the TXT record used for?

By on Tuesday, September 27, 2022

Let’s dive deep into the TXT record. It is one of the DNS records with the most diverse purposes. You can use it in many cases as part of multiple verification mechanisms. 

What is the TXT record?

The TXT record is one of the DNS record types. Its name comes from the word text. The TXT record can contain a text message that can be orientated to people (other DNS administrators) or machines (external sources that want to verify the domain). The message, usually some code, needs to be added to the Forward DNS zone of a domain name, so other people or machines can see that the DNS administrator really has access to the zone. 

The most popular use of a TXT record is to prevent SPAM messages. Multiple TXT records can be used together to verify the domain (the origin of the emails) and to encrypt the individual messages. Without those text records, many emails can get directly into the SPAM folder of the receivers and never be opened.

DNS propagation: What causes it?

By on Wednesday, June 29, 2022

Most likely, you’ve heard the phrase “DNS propagation,” but you’re not really clear what it means. You’re not alone, so don’t worry. In that way, in this article, we will give a simple explanation of DNS propagation.

What DNS propagation means?

The act of updating and disseminating all of your new changes to the Domain Name System is known as DNS (Domain Name System) propagation. And it’s all over the internet.

If you manage a network or own an internet business, you are aware that the DNS needs to be changed frequently. For example, a DNS record may need to be updated, a new one added, or it may need to be edited to replace IP addresses.

​How does Dynamic DNS work?

By on Sunday, June 12, 2022

If you are an administrator of a network and you still don’t use Dynamic DNS, convince your boss to get it today! Yes, it will give you a hand you need and time to breathe! To administrate networks is a really tough job. Try to make it easier when possible. 

​What is Dynamic DNS?

Dynamic DNS (DDNS) is a method for automatically updating the IP addresses (A or AAAA records) when hosts or devices change. It helps to keep a name server automatically updated. It updates almost in real-time and without the administrator doing it manually! Now for sure, you are interested!

DNS resolution: Essential Process You Should Know

By on Monday, May 16, 2022

Today’s article will explore the DNS resolution – its purpose, how it works, and why it is critical for you and your business. So, if this sounds interesting to you, let’s take deep into Domain Name System resolution.

DNS resolution – Definition

DNS resolution is the process of translating a domain name into an IP address (IPv4 or IPv6). Without it, the Internet would function in a very different way. However, it occurs behind the scenes because typical consumers are unaware of the situation. People are accustomed to inputting a simple domain name into their browser, which loads the appropriate website. However, the user’s DNS query is routed via numerous servers before receiving a complete response.

By on Wednesday, April 20, 2022

The topic of today’s post is FTP vs UDP. If you’re looking for information on what they are and how they differ, you’ve come to the right place. So, let’s explore them a little bit more and see then the differences.

FTP – definition

FTP (File Transfer Protocol) is a network communication protocol that is used to exchange data between devices. A TCP/IP connection can be established between the two. FTP (File Transfer Protocol) is a network protocol that allows a user to connect to a server and download files, websites, or applications from other services. Users use FTP to download data to their personal devices.

FQDN – What is it and when to use it?

By on Wednesday, March 2, 2022

FQDN is an essential part of the Domain Name System. If you want to learn more about it, you are in the right place. In this article, we will see what it means and why it is important. 

FQDN – meaning

The term “Fully Qualified Domain Name,” or FQDN for short, is a domain name that specifies its exact location in the Domain Name System’s tree structure. It is also sometimes referred to as an absolute domain name. Every domain level, including the top-level domain and the root zone, is specified. It is the most thorough method of composing a specific domain name for a host or device.

A record: Fundamental DNS record you should know

By on Thursday, February 17, 2022

The most popular and most commonly used DNS record is exactly the A record. But, if you are just starting managing your network and you haven’t heard about it, don’t worry! Here is a little bit more information about it!

A record explained

The A record, also commonly known as address record, is a DNS (Domain Name System) resource record. It has the essential purpose of linking a domain name to its IP address (IPv4 address). Therefore every time a user desires to connect and explore a specific website, its browser is going to require the IP address which is provided with the A record. Thanks to it, it is going to understand exactly where that website is hosted and connect to it without any difficulties.

As we mentioned, the A record holds inside an IPv4 address, a 32-bit address that includes four combinations of digits divided by dots.
