DNS zones contain the records for mapping domain names to IP addresses or other information. The resolution of a domain name to its assigned information is also referred to as forward resolution, and the DNS zones associated with such processes are often referred to as forward zones. [2]
The registry is the manager of a national ENUM zone. The registry forms, as it were, the top of the national ENUM hierarchy and ensures that reference is made to the registrars’ servers on which the access information is located. Because of the hierarchical structure of the DNS, there can only be one registry for every national ENUM zone.
A registry operator, sometimes called a network information center (NIC), maintains all administrative data of the domain and generates a zone file which contains the addresses of the nameservers for each domain. Each registry is an organization that manages the registration of domain names within the domains for which it is responsible ...
DNAME: 39 RFC 6672 Delegation name record: Alias for a name and all its subnames, unlike CNAME, which is an alias for only the exact name. Like a CNAME record, the DNS lookup will continue by retrying the lookup with the new name.
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com.
The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. the wide concept "income" has a relation to the more narrow concept "net income".
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address (e.g.IPV4, IPV6 but MAC Address) allocation so everyone has a unique identity (e.g. Registrar and Registrant) and will not be replicated, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols ...
The Routing Assets Database (RADb), formerly known as the Routing Arbiter Database is a public database in which the operators of Internet networks publish authoritative declarations of routing policy for their Autonomous System (AS) which are, in turn, used by the operators of other Internet networks to configure their inbound routing policy filters.
