Come on, learn more about what's behind a domain...
What is a DNS server?
DNS (Domain Name System) is an amazing technology that helps you open Internet addresses.
Any device connected to the Internet has an IP address; just like web pages, to access them you need the IP address of the server where they are stored.
However, these unique numeric sequences that allow access to web pages and identify devices from anywhere on the network are very long, difficult to understand and memorize; for that reason, The use of what are known as "domains", which are the translation of the numerical sequences into a name that is easy to remember, is used.
It is important to explain that the devices and servers that make the links in the network work better with numbers, therefore, they perform the name resolution process to collect domain names and then confront them with the numerical sequences (their corresponding IP addresses), all this is what a DNS (Domain Name System) server does.
In short and in simple and common words for anyone reading this article, A DNS server is like a physical machine that translates domain names into IP addresses, and vice versa.
How does DNS work?
When a user types the domain name in the address bar of his device, he is taken to the site he wants to visit. This task, which seems to be instantaneous, has several steps that are called "DNS resolution process"
To better explain how the DNS server works, we will give you an example of how the resolution process works.
If you wanted to go to the ClickPanda you must enter the domain name clickpanda.com in the browser address bar, this action you just performed is, in technical terms, send a DNS request.
The next step is your device will check if it has previously stored a DNS record for the domain you have submitted, look in its hosts file and in its cacheHowever, if no matching IP address is found in the hosts file and cache, your DNS query or request will be sent to a network of four DNS servers.
How to manage your DNS
Each web page has a DNS associated with it, which can be managed by the owner by contacting his hosting service. In the case of ClickPandaDNS can be managed through the technical support.
