Dynamic DNS (DDNS) ServicesThe Domain Name System (DNS) provides the mechanism for translating internet domain names into numeric Internet Protocol (IP) addresses. The DNS makes using TCP/IP-based applications much more friendly, by enabling users to specify network locations by name rather than number.
The Internet Corporation For Assigned Names and Numbers or ICANN is responsible for managing and coordinating the DNS to ensure universal redundancy. ICANN is the global, non-profit, private-sector coordinating body acting in the public interest. ICANN ensures that the DNS continues to function effectively by overseeing the distribution of unique domain names. Among its other responsibilities, ICANN oversees the processes and systems that ensure that each domain name maps to the correct IP address.
At the core of the DNS are computers, root servers to be exact. They are coordinated by Internet Corporation of Assigned Names and Numbers. These servers provide resolution for Top Level Domains TLD's. In an Internet address such as dyndnsservices.com, the .com part is known as a Top Level Domain, or TLD. The root servers contain all the Top Level Domain registries, the global registries such as .net, .org, etc. and the location specific registries such as .ca (Canada).
The root servers store Name Server information for a Top Level Domain Name TLD. When an internet address such as dyndnsservices.com is queried, the root servers will return the Authoritative Name Servers IP addresses for dyndnsservices.com. In turn, the resolving DNS Server will query the Authoritative Name Server to determine an Internet Protocol/IP address for dyndnsservices.com, and in turn pass this information on to the end user.
