Here’s a quick rundown of the most useful DNS terms. Learning the complex structure of the Domain Name System as a beginner can be extremely frustrating. But, if we start explaining, everything will become much more straightforward and make more sense.

Domain Name System (DNS)

The Domain Name System, or DNS, is a critical component of the Internet. It’s a global naming database that converts internet domain names to IP addresses (Internet Protocol). DNS is a multi-level hierarchical system that is decentralized. Humans no longer need to remember long and complicated numbers (for example, 213.45.178.32) in order to access and explore every website thanks to this technology. Instead, visitors can type the domain name directly into their browser and go to their selected web page.

Dynamic DNS

Dynamic DNS is the second term in our list of DNS terms. Dynamic DNS (DDNS) has the advantage of automatically updating and changing the host’s IP address.
