Although Content Delivery Networks were around since the 1990s, they have only recently made big strides for both small and large corporations. Content delivery platforms are an essential component of the internet infrastructure. Without CDN hosting thousands of websites will be slow to load, crash and then go offline. That being said, if you’re new to the technology, we’re here to answer one of the most searched questions online today: how does CDN DNS work?

For this article, we’ll talk about CDN hosting, examine the variables that make the best CDN, and why your website needs it to survive the new digital era.

How does DNS work?

A DNS request is always the first to be made by a web browser when it makes a request for resource information. This is similar to looking up a contact in your mobile’s contacts list. Once your browser has provided the domain name, an IP address will be expected. The IP address allows the browser to directly connect to the webserver. Websites and blogs with smaller domain names generally only have one IP address. Larger web applications, however, may have multiple IP addresses but still use one domain.

In other words, it is easy to understand how CDN DNS works

You can play videos, enlarge photos, open new links, download files, and make requests through the internet every time your device does. Your international visitors will consume your web content much quicker if your website has CDN hosting. If it does not, they will request that your website be moved to the origin of your web host.

If your site is hosted in Chicago by an origin server, all requests from your site visitors will still have to go to Chicago. It’s fine if your primary market is located in Michigan or Ohio. These users will enjoy high-quality browsing. Your site can load slightly later if you have visitors from New Zealand or Tokyo.

What is DNS and the best CDN?

It is easy to get carried away by large CDN hosting companies. Branding teaches us that the best CDN must be the largest. So, it is correct? But it’s wrong. It is important to remember that each website is different and that businesses do not need the exact same CDN. You might not find the best CDN for your website, and vice versa.

One of the most important aspects to consider when signing up for a provider is their distribution network. What number of Points of Presence do they have? Do they have data centers in the countries and regions that are most important to you? These are critical because they help reduce latency. While it is obvious that larger CDN companies have many locations, there are still other questions to be asked.

  • These rates on the CDN market are justifiable.
  • Are there other CDN providers that have the same PoPs my business needs the most but at a cheaper price?

Your unique business and website needs will make the CDN best.

Do I need CDN hosting for my website?

CDN hosting companies manage more than half the internet. Even though this is a significant fraction, it doesn’t necessarily mean that your website should be included in that half. If you are deciding whether it is time to sign up for a provider, take a look at the question “How does CDN DNS work?”

CDNs are used to relay your web content to users far away from your web host origin. A CDN is not necessary if your site serves a specific market that is close to your webhost origin. A CDN is smart if your site has a growing audience coming from all over the globe. You’ll be able to reach a larger audience and will naturally attract more customers. Video-streaming sites, social media companies and journalism agencies, as well as the eCommerce industry, are prime examples of digital empires that greatly benefit from CDNs. Their digital havens wouldn’t load quickly and it would be difficult to segment global audiences without CDNs.

You should not overlook the immense benefits that quick-loading websites offer.
