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.

The concept of DNSSEC

The collection of security extensions known as DNSSEC gives DNS authentication and data integrity.

The Internet Engineering Task Force (IETF) developed it in the 1990s. Its principal objective is to offer an authentication mechanism that uses digital signatures based on open cryptography to demonstrate the data’s origin. With a private key, the data owner can certify the security of DNS data (DNS records). Each recursive server can authenticate the source of the data by comparing it to the public key.

The root server is at the top of the trust chain, which extends down to the specific hostname. Except for the root zone, which has nothing above it, each zone is signed by the one above it.

The recursive server will drop data and try again if, for any reason, it cannot authenticate it. Be safe rather than sorry.
