Here a short list of the most popular DNS terms. In case you are just starting to explore the world of tech and DNS, you should be familiar with them.
Domain Name System
Domain Name System, or just for short DNS, is a worldwide system that serves for linking the domain names to their IP addresses. It has a decentralized multi-level hierarchical structure. It is very helpful and beneficial for people. Without DNS, humans would have to type and memorize IP addresses which is a challenge. Thanks to it, we are able to use easy-to-remember domain names.
Anycast DNS is a routing mechanism that helps for easier and faster DNS resolution. It works by establishing one IP address in several name servers which are located in different geographical places. So, therefore when a DNS query is made, it is going to travel to the nearest and available server. That way, any chance for latency is reduced. Besides, if one of the servers is down and unable to answer queries, the rest of the servers are going to handle the load.
