INTRODUCTION
 Given how businesses are slowly but surely transferring to the cloud these 
days, you can bet it’s high time for enterprises and brands to strengthen their 
online initiatives to keep abreast of current trends.
 More than anything, it is Content Delivery Network (CDN) technology that’s 
helped the digital space keep its shape.
 In fact, CDNs now run more than 50% of the internet. But how do CDNs work 
and what are they made of?
WHAT IS DNS SERVER?
 Consider the Domain Name System (DNS) to be the contact list of the world 
wide web. 
 Every time you key in domain names such as ‘youtube.com’ or 
‘belugacdn.com’ on your browser, DNS is accountable for determining the 
accurate IP address for whichever site you’d like to access.
 More thoroughly put, a DNS server is a device that houses hostnames and 
their corresponding public IP addresses.
HOW DOMAIN NAME SERVERS WORK
 The whole Domain Name System science can be complicated, but to simplify, 
hostnames (belugaCDN.com, for example) are converted into device-friendly IP 
addresses, these usually come in the form of numbers and dots in between 
them.
 Additionally, the devices that request for website access receive IP addresses 
only.
 In other words, a translation happens between what a site visitor keys in onto 
a browser and the device-friendly IP address.
WHAT ARE THE DIFFERENT TYPES OF DNS 
SERVER?
The number of how many types there are may vary depending on the source, but 
there are usually three acknowledged DNS server types.
 DNS Resolver
 DNS Root Server
 Authoritative DNS Server
 Legends of TLD
WHY IS DNS SECURITY IMPORTANT?
 One thing that’s demanded from almost every web traffic is Standard DNS queries.
 This creates a leeway for DNS exploits like man-in-the-middle attacks and DNS 
hijacking.
 A lot of modern businesses are exposed to several DNS server security risks 
because they don’t utilize a whole lot of DNS servers.
 DNS root servers, or simply root servers, are name servers that are accountable for 
DNS functionality and the general flow of the internet.
CONCLUSION
 As every day passes, more and more websites sign up with a provider.
 That’s a solid fact, given how more than half of the entire world wide web is managed by CDNs.
 The whole point of singing up with a provider to start with is to reduce latency and improve web 
page loading speed.
 It’s important to understand that web host origins aren’t built to accommodate hundreds and 
thousands of site visitors all at once.
 If your site is also composed of a ton of dynamic media, getting a CDN is a smart choice, too.
