Purpose and Advantages of GeoDNS

By Bob on April 18, 2022

GeoDNS is the topic of today’s article. First, we will explore it in detail: its purpose, how it works, and its advantages.

GeoDNS – what is its purpose

GeoDNS stands for global traffic director or simply traffic director. It is an effective method for optimizing traffic to domains through the use of geographically based routing. It is also regarded as a cloud alternative for load balancing. In addition, it has a positive impact on network performance.

How does it work?

GeoDNS operates in a unique way. How? To begin, when users query your site, their requests are routed through DNS servers. If you use GeoDNS, you will be using multiple DNS servers located all over the world. This is determined by the DNS service provider you choose. That is, these servers will search their database for each user’s IP address and compare it to the information they have on file for that IP address. The traffic is subsequently forwarded to a predefined IP address, which is usually the one closest to the query’s origin.

Advantages of using GeoDNS

GeoDNS could be really beneficial. Here are some of its main advantages:

  • It’s simple to use. When it comes to setting it up, you will have no problems. After that, everything will operate on its own. All you need is a basic understanding of DNS.
  • Monitoring the DNS. One of the most critical benefits is that it could also keep track of your DNS. It might also be set up such that IP addresses on your blacklist are blocked. As a result, complications will be avoided.
  • Traffic redirecting. You may establish a comprehensive CDN with GeoDNS. That way, you may host your website on multiple servers and use GeoDNS to automatically guide customers to the version of your site that is closest to them. That method will also serve as a load balancer for you. Your network will run without a hitch.
  • Implementing Geo-restrictions. You could set geo-restrictions based on your users’ IP addresses (location). You have the option of choosing who will be allowed to see specific kinds of information. This is particularly handy when dealing with intellectual property, such as videos, music, and photographs.

Who is GeoDNS for?

GeoDNS could be an excellent solution for a variety of companies. The great majority of large organizations with a global presence, on the other hand, are likely to reap the most benefits from using this type of service. Also, content platforms that serve a worldwide audience and e-commerce websites that require a high level of uptime.

Conclusion

Let’s review. GeoDNS is a global traffic director. Its primary purpose is to distribute the traffic. Its main advantages are that it redirects the traffic, manages geo-locations, and monitors the Domain Name System. In addition, it is really easy to configure. So, it’s worth giving it a chance!

Why use a CDN?

What does CDN mean?

CDN is an acronym for Content Delivery Network. It is a network of data centers, and proxy servers spread in several and strategic points around the world.

The networks’ servers at every location are named as a point of presence (Pop). Each one of them has its cache memory data for users of the specific area. This is a service that you can have besides your primary web hosting. It is a bonus to cache multiple copies of data and arrange them in a way that users’ access is ensured. 

CDN was created in the late 90s.’ The purpose is to solve traffic jams on the Internet. It is also improving availability and the overall performance of the Internet.

In present days the need for delivery content has grown progressively, and the use of CDN too. Just think about all the possible content that is circulating over the Internet. For example like, documents, media files, text, software, social media, and many more.

How does it work?

The concept is simple. On the way are DNS resolvers that analyze the DNS request. Depending on the request’s source, they will provide the IP address of the closest cache server. They are called delivery nodes by some service providers. Those DNS servers are placed strategically in different locations. Based on your DNS provider, you can have multiple, and you can be able to put even more in your most significant area.

You can use a service called GeoDNS, depending on your provider, of using regular DNS. With it, you can set different IP addresses for the different regions. 

In such a way, you won’t send the whole traffic to the same origin. You can manage to have the needed number of web hosting located in the crucial areas for you.

Those servers you will use as cache servers, and you will set their IP addresses for the closest DNS server. Thus, the DNS request will perform very fast to the DNS resolver that can present an answer. Then it will redirect to the cache server, and it will save a lot of time.

For whom is CDN intended?

For everybody! Yes, everyone could use CDN. Like for example, a media company. If you have one, CDN could be the one thing to help you to distribute content to some more locations. It could be very beneficial for e-commerce sites, too. Primarily if they operate on various markets like many states – The US. Or maybe different countries like the European Union is your target market, it could be a perfect fit.

Blog sites, news sites, online services, and a lot more are not an exception. It all depends on your needs. 

The truth is that some of the CDN prices are very affordable. Even for a small company or a start-up, it won’t be a problem implementing CDN and paying a monthly subscription. And that is amazing!
