Domain_Names guides users to subcategories which contain all resources and services having to do with Domain Name Services. The Domain Name System (DNS) is a distributed database used by computer systems to map between hostnames and IP addresses, and to provide electronic mail routing information. Each site (university department, campus,company, or department within a company, for example) maintains its own database of information and runs a server program that other systems across the Internet can query. The DNS provides the protocol which allows clients and servers to communicate with each other. This category and its sub-categories include the companies that provide the resources to make this system work, companies that provide the resources to end users for use or resell and sites that discuss issues in the system.
An initiative of the Mozilla Foundation to record domain name suffices such as ".com" or ".co.uk" under which sub-domains for different entities are registrable. Includes FAQs, the list file, and instructions for registrars to submit changes.
