Why are only 13 root servers available in the world?
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.

How many root servers exist?
As a keen observer of the digital landscape, I'm curious to delve deeper into the infrastructure that powers our online world. Specifically, I'm wondering about the backbone of the internet's domain name system. So, I must ask, how many root servers actually exist? These servers, tasked with maintaining the master directory of all top-level domains, are crucial to the smooth functioning of the internet. Their redundancy and distributed nature ensure resilience and reliability, but just how many of these guardians of the digital realm are there?
