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.
