About the DNS Root Server Speed Tool

The DNS Root Server Speed tool is designed to return latency information, which define the root zone of the DNS service of the global public Internet. Root Servers are administered by ICANN (Internet Corporation for the Assignment of Names and Numbers). All of the common, well known top-level domains (such as .biz, .com) and the ccTLDs (country-code TLDs like .us, .de, or .cn) are present in the zone file of the root servers.
