​Unicast DNS explained

To understand what Unicast is about, let’s briefly review the concept of routing. It’s a process of picking the most convenient path for the traffic in a network or across many networks.

If you think about networks, the Internet, for instance, there is constant communication. A continuous exchange of data that travels around, divided into packets. To deliver such an amount of data packets, from their source to their destination, definitely require a smart routing. 

Routing works based on routing information base (RIB) or routing tables. They are records of data that include the routes to different network destinations. Sometimes, they also have specific distances related to those routes. Administrators create these tables because they permanently monitor network traffic. Or they can be built through the routing protocols. That’s what they are made for.

There are different routing methods. Unicast is one of them.


DNS: What is it?

DNS is a complex topic, and it deserves special attention. A long time ago, there was no Internet. However, today we can not imagine the world without it, and DNS is one of its main pieces. So let’s explain a little bit more about it. 

What does DNS mean?

DNS stands for Domain Name System. It is an essential part of the Internet that serves a great purpose. This infrastructure makes the experience on the Internet for humans simple and easy. The functionality it provides is enormous. At its core, the DNS has a large database with the existing domain names and the IP addresses that correspond to them.
