Root Zone (Root Servers)

The root zone is the very top of the DNS hierarchy — the master list of every TLD and which registry servers are authoritative for it. It is served by the root servers, a globally distributed set of systems reached at thirteen named addresses, and the zone's contents are maintained through IANA. Every domain lookup that isn't already cached starts here: a resolver asks the root where to find .com, then follows the chain down. The root zone is the internet's naming anchor — and it is untouched by tokenization, which adds a wallet-controlled ownership layer above the existing DNS rather than replacing the root.
