DNS zone: 4 Types You Should Know

June 24, 2022 Pavel No Comments DNS DNS records DNS, DNS Namespace, DNS server, DNS zone, Domain Name System, Master (Primary) DNS zone, NS record, Parked zone, PTR rcord, Resource Records, Reverse Domain Name System zone, Secondary DNS zone, SOA record, TCP/IP

Today we will talk about the DNS zone. First, we will explore its purpose and then its different types. Finally, we will explain how you can locate your DNS zone. Let’s start!

DNS zone description

A DNS (Domain Name System) zone is a database containing Resource Records from a single DNS Namespace. Another way to say it, these zones are designed to make administration simple and redundant while also assisting in improving availability and performance. Additionally, you could see the DNS zone as a horizontal platform that connects all of a corporation’s subdomains.

As an illustration, if we have the domain name picusha.net and a zone called picusha.net inside of a DNS server, we may construct Resource Records for all of the TCP/IP devices inside the zone. This DNS server has been given permission to handle all DNS requests for picusha.net domains, including www.picusha.net, info.picusha.net, etc.

How does DNSSEC add an additional level of security?

DNSSEC is the most effective technique to secure your Domain Name System. We’ll explain why, what the phrase implies, and how you can benefit from it in this article. So, let’s keep it going.

The explanation of DNSSEC

DNSSEC is a collection of Security Extensions for the DNS that adds authentication and data integrity.

The Internet Engineering Task Force (IETF) invented it in the 1990s. Its primary goal is to provide an authentication method that uses digital signatures and public cryptography to prove the data’s origin. The data owner can use its private key to sign DNS data (DNS records) and ensure that the information is secure. Each recursive server can validate the data’s origin by comparing it to the public key.

It’s a complete chain of trust, beginning with the root server and ending with the exact hostname. Except for the root zone, which has nothing on top of it, each zone is signed by the one above it.

If the recursive server cannot authenticate the data for some reason, it will discard it and try again. It’s always better to be safe than sorry.

The topic of our discussion today is the Monitoring service. If you wonder what its main purpose is, why it is so beneficial for you and your business, and where you can find you, you are in the right place. So, let’s not waste any more time in idle talk, and let’s explore it!

Monitoring service – Definition

Monitoring service is critical for delivering dependable service and a positive user experience. It also helps to identify problems with your services such as web, DNS, email, and so on. In addition, it provides precise information about the state of your servers and assists you in quickly identifying and resolving various issues.

You also have the option to monitor and notice the status of your servers in real-time. Any issues, such as a component failure or extremely slow traffic, will be straightforward to recognize and respond to.

Automatic notifications are also provided through the Monitoring service. As a result, if a problem arises, you will be notified via email, SMS, or other methods.

Interesting DNS Terms & Definitions

March 24, 2022 Pavel No Comments DNS Anycast DNS, DNS, DNS cache, DNS propagation, DNS query, DNS server, DNS terms, DNSSEC, Dynamic DNS

Here are some interesting DNS terms you may not know yet. They are helpful both for beginner DNS administrators and more advanced ones.

Dynamic DNS

Dynamic DNS automatically updates your IP address every time it is replaced. The Internet Service Providers (ISPs) are commonly changing it since it is easier for them to manage their large networks. For that reason, it is really useful to implement Dynamic DNS, for example, for your CCTV cameras for surveillance.

Anycast DNS

If you want to boost the DNS resolution process of your domain, you should consider Anycast DNS. It is a routing mechanism that works by placing one IP address into several name servers that are positioned in different points of the world. That way, the DNS request (DNS query) takes the shortest path, and the closest server provides the needed data.

DNSSEC

DNSSEC (Domain Name System Security Extensions) brings extra protection to your DNS (Domain Name System). It applies cryptographic authentication for the DNS data (DNS records) that goes around the Internet. Besides, Domain Name System Security Extensions provide insurance for the origin of the DNS data and its integrity.
