| | ICANN | Toward a Statement of the ICANN Mission |
 | | The DNS root zone file consists of a list of all top-level domains in the authoritative public DNS (currently 259 TLDs), along with the names and IP addresses of the primary and secondary name servers that are authoritative for each TLD. |
 | | Through its Root Server System Advisory Committee (RSSAC), which consists of the root name server operators and invited experts, ICANN is also responsible for developing and implementing policies relating to, for example, the distribution, location, and identity of the root name server operators. |
 | | For example, when planning and implementation testing are complete, ICANN will operate a dedicated primary root name server, a significant security enhancement that will eliminate the need of the root name servers to rely on one of the machines that handles public DNS queries to also provide the authoritative version of the root zone file. |
