Understanding the benefits of Round Robin DNS

Posted on by Owen

Are you looking for a way to improve your website or application’s performance, reliability, and security? Round Robin DNS is a great tool that can help you achieve these goals. In this article, we will take a closer look at the benefits of Round Robin DNS and how it can help you manage the traffic on your network.

What is Round Robin DNS?

Round Robin DNS is a DNS load-balancing technique that helps to balance the traffic load on a network by distributing the requests between multiple servers. It works by rotating the IP address of each server in the network so that the traffic is evenly distributed. This allows the network to handle more requests without running into performance issues. It can be used to increase the availability of websites, improve response times, and provide better scalability. It can also be used to improve the security of a website by preventing malicious traffic from one server from affecting the rest of the network. That is why, it can be a great tool for businesses that need to manage a large amount of traffic in a cost-effective way.DO

How does it work?

Round Robin DNS works by assigning multiple IP addresses to a single domain. When a user makes a request to a server, the DNS server will respond by sending back all the IP addresses associated with the domain. The DNS server will then “rotate” the order of the IP addresses so that a different IP address is used each time a request is made. This way, the web traffic is distributed more evenly across the multiple servers associated with the domain. Since each server is only handling a portion of the traffic, the server will be able to respond to requests faster. This can result in a better user experience and improved page loading times. Therefore, it is an essential tool used by web hosting companies to ensure that their servers are able to handle the load of incoming requests.

Benefits of Round Robin DNS

Here are some of the key benefits of using Round Robin DNS:  

  • Improved Performance: Round Robin DNS can help improve the overall performance of your site or application by distributing the load across multiple servers. This means that a single server won’t be overloaded with too many requests.
  • Increased Reliability: Having multiple servers to serve the requested information, Round Robin DNS helps ensure more reliable service. If one server were to go down, the other servers would still be able to serve up the requested data, resulting in fewer DNS outages.  
  • Cost Savings: By using it, you can reduce the cost of running a website or application by taking advantage of multiple servers. This can help save money in the long run by cutting down on the need for additional hardware and software licenses.  
  • Increased Security: It can help protect your website or application from malicious attacks by distributing the continued traffic across multiple servers. This can help make it more difficult for attackers to target a single server and potentially gain access to your sensitive data.

Conclusion

In conclusion, Round Robin DNS is a powerful tool that can help businesses increase the performance, reliability, and security of their websites and applications. By distributing the load across multiple servers, businesses can reduce costs, improve response times, and better protect their sensitive data. For any business looking to maximize the performance and availability of its website or application, this is an essential tool.

Complete breakdown of CDN

Posted on by Owen

Providing your customers with the best user experience is essential. A CDN is the perfect way to deliver content to your customers quickly and reliably. Find out more about this amazing technology and how it can benefit your business.

What is a CDN?

A Content Delivery Network (CDN) is an interconnected collection of internet servers that allow users to access content from a single source. CDNs are built to accelerate web content delivery, such as videos, audio, and images. Using a geographically-distributed network, CDNs can quickly transport content to users all around the world. CDNs work by caching or storing copies of content on servers worldwide. This means that when a user requests content, it can be served from the nearest CDN server. This will minimize the distance and overall time it takes to deliver it. As a result, CDNs are a great tool for websites that are designed to reach a global audience, providing faster web page speeds, improved security, and more reliable performance.

What are the different CDN types?

  1. Push CDN: It stores files and delivers them to the user via an origin web server. Large companies and organizations typically use it.
  2. Pull CDN: This type of CDN requires users to enter a URL to retrieve content from servers scattered across the globe.
  3. Streaming CDN: A streaming CDN is used for delivering media and other files over the internet in real-time, such as when viewing videos or listening to music.
  4. Hybrid CDN: It combines both push and pull CDNs that serve content from multiple servers worldwide to ensure better performance.

Who makes use of a Content Delivery Network?

Many different types of companies use CDNs to provide a faster, more efficient way of delivering content to users. For example:

  • healthcare
  • governments
  • publishers
  • media outlets
  • gaming companies
  • e-commerce businesses 

By utilizing a Content Delivery Network, companies can ensure their content is quickly and smoothly transferred to customers all around the world. They will provide customers a high-quality user experience regardless of location or device used.

CDNs have changed how companies serve their content and now help ensure that customers can quickly access whatever they need with ease and speed, which was not possible in the past.

Does CDN need DNS?

A Content Delivery Network does need DNS to function correctly. DNS is used to resolve domain names to IP addresses, allowing CDN content to be requested from the correct geographic location. This ensures that content arrives quickly, reliably, and from the closest server to the user to minimize network latency. Without DNS, a user’s requests would take longer to process, resulting in longer wait times and slower speeds. By utilizing the power of both DNS and CDN technologies, companies can ensure their customers have an optimal experience when using their online services or products.

Conclusion

CDNs are an essential part of any modern business, providing the ability to quickly and reliably transport content to users worldwide. By utilizing it, companies can ensure their customers have the best possible user experience, regardless of location or device. In addition, by combining a CDN with DNS technology, companies can ensure maximum performance and reliability of their content delivery. A Content Delivery Network is a way to go if you want to give your customers the best experience.

GeoDNS: How to start using it?

Posted on by Owen

So you want to start using GeoDNS. Congrats! That means your business is growing or already big.

Step 0. Know what GeoDNS is?

A Geographical Domain Name System or GeoDNS is a method to distribute the traffic considering the location where the DNS query was generated. GeoDNS involves a network of name servers located in strategic points of the planet. These servers have different IP addresses for the same domain based on the region or area they cover, and that represents an incredible speed boost for the DNS resolution.

The trick of GeoDNS is that it redirects the traffic based on the DNS clients’ IP addresses.

How to start using GeoDNS?

Step 1. Check your needs

Consider the real needs of your business. Analyze if you need such a network of multiple servers worldwide working for you. What’s your market? Do you have an international company or a very local one? GeoDNS is a great option for most businesses because it brings many benefits, like speed, efficient traffic distribution, IP filtering, quicker loading time, constant uptime, and redundancy!

But mostly, international companies use it because they receive a high volume of DNS queries 24/7 from clients around the world. Since the queries are produced in very different and far away locations, deploying GeoDNS makes total sense.

Step 2. Research DNS providers

Research different GeoDNS providers. Look for a quality and trustable service. And check that the locations it offers (network) are convenient to cover your specific market needs.

Step 3. Analyze the DNS plans

Analyze the different available plans of that provider. Don’t pay more for extras you don’t need. Calculate the number of DNS queries you expect to be sure the plan will cover your needs. Read carefully all the policies for payment, contract cancellation, technical support, the fine print, etc., not to be surprised.

Step 4. Configure your network

Once you get the service, your provider will run the GeoDNS, but you have to configure it on your system. You just need to add an IP address to every server in the world you choose to be close to your clients. It is easy. Just be careful while typing the IP addresses.

Step 5. Test

Run a test. Usually, the interface of most providers includes a tool to test (like Ping) what you configure and the changes you make. Test that the servers respond to the IP address you added to them.

Step 6. Your system is ready to start using GeoDNS

Wondering what will happen next? Well, when a user sends a DNS query to visit your domain, the DNS resolution process will be triggered, but this time, GeoDNS will make a big difference. The DNS server will read the IP address of the users to get their locations. Then, their queries will be sent to the nearest server to be processed. The answer to them will be quick, and the loading time will be reduced considerably.

Conclusion

GeoDNS is a great technology! If your company is steadily growing, already international, or if it is on the way to reaching that level, start using it today and enjoy its multiple benefits.

DNS outage – Everything you need to know

Posted on by Owen

Imagine you have been preparing for months for the special sale of your e-shop. Clients impatiently wait for the countdown to point out the beginning. And when they all try to access your website, your domain name can’t be loaded. Clients receive an error message on every try. Yes, pretty sure your e-shop is experiencing a DNS outage.

And the issue is that this can make your clients angry or disappointed. You will lose money, and your reputation can be affected.

Better be prepared and know more about DNS outages. Here you have everything you need to know. Including how to prevent them!

What’s a DNS outage?

DNS outage or DNS downtime, as it’s also called, is a time interval during which a domain name can’t be resolved to its IP address.

The Domain Name System (DNS) and its resolution process are essential for accessing any domain name. If there’s a failure causing the DNS not to work, the necessary translation from domain name to IP address won’t happen. So the domain won’t be located, and therefore, its content won’t be accessible to visitors.

What causes a DNS outage?

A DNS outage can happen due to different causes:

  • Human errors. Yes, humans are behind a large number of DNS outages. For example, a script error, a misconfiguration, or a single typo on the IP address of the domain name can cause a DNS failure.
  • DDoS attacks. If the traffic overloads sent by attackers make your DNS servers crash, the domain name will be down.
  • Lack of redundancy. Of course, you can run your domain name with only an authoritative server, but it can be risky. Software or hardware failures, updates, regular maintenance, or a cyber attack can shut it down.
  • Propagation delays. Online businesses must delete, edit, or add different DNS records regularly. Propagating these modifications or updates across a complete network can take time. Technically, this is not an error or a cause of a DNS outage, but visitors who can’t reach your domain will perceive it like that. Once the DNS propagation gets completed, everything will be ok.

How to prevent a DNS outage?

Look for redundancy

Redundancy is key! You can use Secondary DNS services. Using multiple Secondary DNS servers, you can set them as Secondary authoritative nameservers. In case the Primary gets attacked or suffers downtime, the Secondary servers will answer the DNS requests of your clients.

Use DNS failover

This technology can automatically redirect traffic to a different server. In case of a server’s failure, DNS failover will get activated for the DNS resolution process to keep going. So your website will be accessible even if a server falls.

DNS load balancing

Load balancing is a great practice to avoid a DNS outage. While distributing traffic through the available servers, it can handle traffic spikes and prevent servers from being overloaded.

Conclusion

Preventing DNS outages on your online business is possible! Take action now! Don’t let it stop your operation.

Benefits of using a Monitoring service

Posted on by Owen

Precisely what does a Monitoring service entail?

Monitoring services are a broad category of goods that enable analysts to check whether IT equipment is online and operating as expected, as well as to address any issues they may uncover. It offers comprehensive information about the condition of your servers, which you use for a number of services, including web, email, DNS, and others. Many Monitoring service plans and options are available, ranging from thorough inspections to advanced tools that can evaluate a product’s performance in great detail and even automate repairs when defects are found. Actually, so-called Monitoring Checks are used to do this. There are many different kinds, and every company offers a selection. TCP monitoring, DNS monitoring, and other popular ones are among the most well-known and frequently used ones. However, many others are also advantageous. So let’s look at the popular ones of them now.

Types of Monitoring service checks

There are various ways to analyze a service’s uptime or downtime. In addition, you are informed if a check is unsuccessful. Here are a few examples of the most typical check types:

  • ICMP Ping Monitoring check

This check offers details on network activity involving a specific domain or IP address. The system tests an IP address using the ICMP ping protocol.

  • TCP Monitoring check

Using the provided IP address (IPv4 or IPv6) and port number in the Transmission Control Protocol, the system establishes a Transmission Control Protocol (TCP) connection.

  • UDP Monitoring check

The computer verifies the precise IP address to the User Datagram Protocol (UDP) port number you or your system administrator specified.

  • DNS Monitoring check

The hostname that you or your administrator provided is checked in DNS by the system. You can also select the query type for the specified IP address.

Benefits of using it

You should employ a Monitoring service for a number of good reasons.

  1. Unwanted power outages can be avoided.

You might be able to identify and prevent a number of problems that lead to downtime and DNS outages with the help of a monitoring system. It is a straightforward technique. When you have up-to-date information, you can react very rapidly.

  1. You can now see more of your network.

The Monitoring service increases visibility by displaying real-time network performance data, issuing alerts via email and text, and presenting it in an understandable manner.

  1. Better security

Sometimes downtime is caused by fraudulent attacks like DDoS (Distributed Denial of Service) attacks and DoS (Denial of Service), not network issues. Monitored providers will catch any unwelcome infections and keep your organization secure, whether there is an effort to infiltrate an enterprise network or a raging part of spyware is trying to sneak in.

Conclusion

Huge congrats! You’re getting closer to using the Monitoring service. Why? Because you understand its objective, advantages, and various check types. So, what happens next? To put it into action. Good luck!
