DNS resolution: Essential Process You Should Know

By Davis 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.

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.

Users use FTP to download data to their personal devices.

FQDN – What is it and when to use it?

By Davis 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.

DNS DNS records

A record: Fundamental DNS record you should know

By Davis 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.

DNS zone – Definition

By Davis on Friday, February 4, 2022

The DNS zone is a plain text file that contains all of the domain’s DNS records. As you may be aware, the DNS is a complex system that functions as a global database of domain names and IP addresses. Therefore, the domain name system would not work without a dns zone.

DNS Servers

Authoritative DNS server explained

By Davis on Friday, January 14, 2022

There are different types of servers – TLD, root, recursive, authoritative DNS server etc. If you think that all of them are the same and comply with the same objectives, that’s a mistake. They are teammates, but definitely, there are differences between them. Today let’s talk about Authoritative DNS servers. What exactly are they for? Why do you need them? Here it will be explained!

What is an Authoritative DNS server?

An authoritative DNS server, also known as Primary DNS server, is the holder of the zone file that contains the DNS records. And in this case, we don’t talk about a copy of them but the true DNS records. For this reason, it’s the exact and only place the master zone can be managed from and where edition or any kind of modification to DNS records can be made.

A complete breakdown of Anycast DNS

By Davis on Tuesday, December 21, 2021

We will show you everything you need to know about Anycast DNS. A complete breakdown of Anycast DNS that will explain to you the functionality and purpose of this service.

What is Anycast?

Anycast is a routing scheme that is perfect for use with DNS. You can use the same IP address (Anycast address) on multiple nodes. It is more about the configuration of routers and routing than servers.

Each packet sent to an Anycast IP address may reach a different server in an Anycast DNS scenario. The anycast address is shared or configured in multiple different servers across the network.

They are routed to the IP address with the best network metric. This is the nearest server in most cases, but it is not a must. The metrics could be various factors like bandwidth, cost, load, or reliability, etc.
