The Root Server Technical Operations Association maintains a map that shows the location of all of the world’s root name servers. Over 50 of them are F Roots, operated by ISC. If you are perplexed that over 50 (the number of F-root servers) is greater than 13 (the number of root name servers), you can read about the “anycast” scheme used to make the servers collectively behave as one server.
Network operators can improve their access to the F Root Nameserver, and hence the reliability of the DNS in general, by peering with ISC at the exchange points where we maintain a presence. For information about peering with ISC, see our Peering Information Page.
On January 4th, 2008, ISC became the first root server operator to sign a Mutual Responsibilities Agreement with ICANN, which identifies mutual responsibilities and is another step to enhance Internet stability.
