Editing Root name server (section)

==Root domain==
The DNS is a hierarchical naming system for computers, services, or any resource participating in the [[Internet]]. The top of that hierarchy is the [[root domain]]. The root domain does not have a formal name and its label in the DNS hierarchy is an [[empty string]]. All [[fully qualified domain name]]s (FQDNs) on the Internet can be regarded as ending with this empty string for the root domain, and therefore ending in a [[full stop]] character (the label delimiter), e.g., "{{mono|www.example.com.}}". This is generally implied rather than explicit, as modern DNS software does not actually require that the terminating dot be included when attempting to translate a domain name to an IP address.

The root domain contains all top-level domains of the Internet. {{As of|2015|07}}, it contained 1058 TLDs, including 730 [[generic top-level domain]]s (gTLDs) and 301 [[country code top-level domain]]s (ccTLDs) in the root domain.<ref>{{cite web|url=https://www.iana.org/domains/root/db|title=Root Zone Database|publisher=IANA}}</ref> In addition, the {{mono|[[.arpa|ARPA]]}} domain is used for technical [[name space]]s in the management of Internet addressing and other resources. A {{mono|[[.test|TEST]]}} domain is used for testing [[internationalized domain name]]s.
