At the core of the global internet are the DNS root servers. These 13 go-to places are at the top of authority when it comes to making sure you can connect to any server with a domain name. What you might not know is that 10 of these 13 root servers are ultimately under US jurisdiction. Should that worry you? I guess not, the current system is quite robust. But I deal in risk assessment and probabilities. And I think this isn't an ideal setup.

@jwildeboer While I appreciate that this isn’t your point, and while this is mentioned in the linked Wikipedia article, I just want to clarify that there are far more than 13 servers: “However, enabled by the use of anycast addressing, the actual number of root server instances—1954—is much larger, as of December 5, 2025.[3]”.

@ximon18 Yes. But the way to reach them goes through the 26 public IPv4 and IPv6 addresses. Anycast and load balancing don't counter the fact that we only have 13 root servers.
