Most frequently used DNS commands

These DNS commands are the most commonly used when we are talking about DNS troubleshooting. This is because they are easy to use and can provide you information about your DNS records and how your network is operating. It doesn’t matter if you are a Linux, Windows, or macOS user. You have multiple commands included in your OS. So let’s see which are the most frequently practiced DNS commands and how you can use them.

Nslookup command

The NSLookup command is one of the frequently used DNS diagnostic commands. The beneficial thing about it is that it is present on all of the popular operating systems (OS). With it, you are able to see all kinds of DNS records. Also, it includes various options.

Use the NSLookup to see all the available DNS records. In the command line, write: 

$ nslookup -type=any

It is going to show you all of the available DNS records for the particular domain. If you want to see a specific DNS record, change the type to NS, A, AAAA, MX, SOA, etc. After the DNS type, you can put another domain name or IP address.

4 things you have to know about load balancing.

If you already have load balancing in mind, it means your traffic has really grown. Congrats on that! 

If you are getting into the topic, here you have the 4 things you have to know about load balancing. It’s a good starting point for you to go deeper!

What is load balancing?

In a nutshell, load balancing is the action of efficiently distributing traffic and workload across different servers. The more available servers, the best chance to distribute the loads and not let a single one get overwhelmed.

There are different load balancers, simple and more sophisticated mechanisms, software, or hardware. Basically, load balancers constantly check servers to be sure they can handle the incoming requests without trouble. Based on this, they distribute the loads as needed.

Why is Secondary DNS service beneficial?

Today we will talk about the Secondary DNS service. It provides additional authoritative nameservers to domain name owners to answer domain queries. But if you want to get deep into its purpose, why it is so important, and how you can get it, you are on the right article.

Secondary DNS service purpose

Secondary DNS is a service that can be used with your Primary DNS. It adds to your name server network by storing copies of the zone file holding your domain’s DNS records. These servers can replicate your domain’s Primary DNS zone file and provide additional points of presence (PoPs). So even if your Primary DNS is down, users can resolve your domain much faster this way! Isn’t it wonderful?

What causes a DNS outage?

What exactly is a DNS outage?

A DNS outage, also known as DNS downtime, is a period of time when the DNS is not functioning correctly. This means that if you look up the domain name, you won’t see its IP address. Instead, users will make DNS requests in order to reach your domain. The DNS recursive server will request the domain’s authoritative nameserver, but it will receive an error message as a response.

3 Steps for better DDoS Protection

DDoS Protection is essential in today’s online world when attacks lurk around every corner. In this article, we’ll go over what DDoS attacks are and three steps you can take right now to improve your Distributed Denial of Service security.

What is a Distributed Denial of Service (DDoS) attack?

DDoS (distributed denial of service) is a type of attack in which cybercriminals attempt to drown a target (network or server) by flooding it with traffic from various sources (infected devices).

There are several forms of DDoS attacks, each of which employs a distinct method for generating traffic. However, in most cases, attackers send a large number of requests to their victim in order to take it down and deny service to legitimate users.

Steps to more effective DDoS Protection

1. Determine what you need to safeguard.

The goals of each organization are distinct. What Internet-facing assets must you defend against DDoS attacks? The type of DDoS protection you require depends on what you need to defend. A DDoS scrubbing network is set up to protect a data center, network infrastructure, and other non-website assets such as email servers. Web assets, such as websites, web applications, and APIs can be protected using a content delivery network (CDN) with DDoS mitigation and web application firewall features.

2. Before you need it, set up a DDoS protection solution.

Choose a DDoS Protection before you need it. There are several additional benefits to avoiding the turmoil, delays, and worry of hunting for DDoS defense when under attack:

  • Your DDoS protection supplier can explain the DDoS protection approaches that would best suit your demands. They can examine flaws in your protection to guarantee you’re entirely protected.
  • Prepare to defend against DDoS attacks. Create the basis for your DDoS protection service and get it up and running.
  • Test and validate your DDoS scrubbing service with your DDoS protection provider.

3. Identify the weak part of your network.

Detects flaws in your networks before a rogue user exploits them. A security audit entails detecting vulnerabilities in your infrastructure so you may patch it up and be better prepared for a DDoS assault or any other cyberattacks. In addition, this will assist you in determining your organization’s risk level, allowing you to maximize any security investments.

What should you do if you’re the target of a DDoS attack?

First and foremost, it’s important to note that just because your website is slow doesn’t always mean a DDoS attack has occurred. It’s usually due to an increase in site traffic. However, if the issue occurs frequently enough, it is worthwhile to take appropriate action. In this case, contact your web hosting company. 


DDoS attacks are a serious threat and could cost you money and customers. You can implement DDoS protection strategies for staying safe and fighting back if necessary. But it’s like playing with fire if you don’t plan ahead!

DNS records

Fundamental DNS records you should know.

DNS records explained.

DNS records set specific rules in a DNS zone. They are entirely made of text, which makes them very light. Zone files are the place where the various types of DNS records are stored.

Every time when a user makes a request, the DNS servers are searching for a particular DNS record type. As a result, there are many different records for the various kinds of requests that could be made. So, let’s make things a little bit more precise and explain some of the most fundamental DNS records.



Complete list of HTTP status codes.

Through HTTP status codes, machines point out if HTTP requests were completed or not and why. Understanding the status codes’ meaning can save you time and effort while trying to fix a failure.

Complete list of HTTP status codes.

An HTTP status code is a numeric representation used by servers to convey the result of a client’s HTTP request, providing information about the success, error, or additional action needed for the request.

There are five categories of HTTP status codes: Server error, client error, redirection, successful, and informational.

Six Benefits Of IPv6

What is IPv6?

IPv6 is the latest version of the Internet protocol (IP). The purpose of Internet protocols is to set specific rules for the devices to send and receive information successfully. The exchange of information is between two hosts. So, for that reason, they have to be able to be identified. IP addresses come to help in this situation to track each host’s location. Finally, the two corresponding IP addresses are acknowledged, and the route is established for the entire data exchange.
