Explanation of Anycast DNS
Anycast DNS is a type of communication or routing technology that enables rapid data transmission and reception. Using this technique, a single IP address can be typed into several DNS servers worldwide. Any of them is capable of responding to the request. The intended outcome is for the server physically closest to the user to respond. The response time is sped up dramatically as a result.
How does it interact?
When a device connects to the Internet, it uses its IP address to communicate with a server. One-to-one communication is the most fundamental form of communication. This is sufficient, and DNS resolution may be possible. However, specific requests will have to travel long distances to reach a server that only has the required data (A or AAAA record) and is located far away. The user will not receive the intended response if the server is unavailable. The query won’t get an answer.
