Could you elaborate on the reason why there are only 13 root servers operating globally in the Domain Name System (DNS) hierarchy? I'm curious to understand the rationale behind this specific number, especially considering the vastness and complexity of the internet. Is it a technical limitation, a design choice, or a security measure? Furthermore, are there any plans to increase or decrease this number in the future, and if so, what factors would influence such a decision? Understanding the intricacies of this system is crucial for anyone interested in the stability and security of the internet.

Given this limitation, it became necessary to find a balance between efficiency and scalability. A large number of root servers would increase redundancy but also increase the complexity of managing and maintaining the system.

Specifically, the practical size of unfragmented User Datagram Protocol (UDP) packets poses a limitation. These packets, being the fundamental units of data transmission in UDP, have a defined maximum size.

Therefore, a decision was made to limit the number of root servers to thirteen server addresses. This number represents a compromise, allowing for adequate redundancy while maintaining manageability.

The thirteen root servers are strategically located around the world, ensuring that DNS queries can be efficiently routed to the nearest server. This configuration optimizes performance and reduces latency for end users.
