Why Is DNS Followed a Centrally Designed Database Model?
DNS follow a central database system, which allows for better management of dns records around the globe. A DNS database is separated into a number of zones, and each zone holds a part of the record. When you type in an IP address, the system automatically looks up the corresponding DNS server and performs the requested operation. Administers are able to add, modify and delete DNS zones as they see fit. Changes made are propagated to all servers that host the DNS zone.
The DNS system is built robustly to make the experience of working with it as smooth as possible. DNS follows an elegant, simple and centralized design to provide an extremely fast internet surfing experience. DNS technology provides a very high level of security for any site. DNS stores a large set of cryptographic algorithms that secures data. DNS is used as a service to provide fast access to information online. This is achieved by making all DNS operations, both server side and client side, highly efficient and reliable.
DNS is built on a foundation of concepts of Distributed Management, or DMS. This concept is designed to provide customers with an online application that will manage their DNS resources. DMS includes not only the basic concepts of DNS such as zone transfers, but also allows clients to make use of their own access control mechanisms to limit the access to certain DNS resources. The ultimate aim of DMS is to provide an easy to use interface for users, so that they can take advantage of their existing DNS management abilities and at the same time have confidence in DNS being well maintained.
There are three main parts to a DNS system. There is a root DNS server, which hosts the entire DNS infrastructure. A zone transfer contains the details of one or more name zones that have been applied to a single IP address. An address belongs to a name zone if it has been delegated to a trusted name server by the client. A record also comprises the details of a name zone and an IP address, which are referred to as an IP-based zone.
DNS meets the first criteria because it is a highly efficient and effective system. With DNS, you can achieve higher response rates from your website visitors, as DNS technology greatly improves the quality and reliability of the DNS system. Another benefit of DNS is that it is a highly flexible system, permitting changes in DNS registration at any time, to make it more adaptable to the needs of your business environment. Because DNS is highly dependable, it can be used as a backbone for other DNS solutions. This means that DNS can be leveraged to provide or establish more advanced DNS functionality, such as reverse look-up and domain locking. This way, you can make the most of your DNS resources.
The second condition, that a DNS system offers support for multiple IP-based zone queries, is fulfilled by DNS. Each DNS server is responsible for keeping up to date records associated with every name that registers with it, as well as for performing calculations pertaining to the amount of time it will take to find a record associated with a given name. Without a highly scalable and efficient DNS system, it will be difficult for companies to meet their need for up-to-date records and to provide end users with fast, accurate results. DNS also meets the third condition of having DNS follow a centralized database model.
One of the benefits of DNS that comes from a centralized database management model is the easy management of dns zone transfers. When a company creates a new web site, for example, it registers the domain name(s) that are used in the name, as well as the site’s internet address and any other details. As more names are registered, the internet database dynamically updates the zone transfer data associated with each name, which allows for quicker and more accurate look-ups when names are transferred. A DNS system that uses a centralized database management system allows for easy transfer of DNS zone records and information between zones and servers.
– Users can easily access the DNS server and its zones. – Administrators can update DNS records at any time. – Updates to DNS record settings do not require any manual approval. – Changes to DNS zone transfers occur synchronously with changes to other DNS zones. – DNS is inherently secure, enabling network security requirements to be met. – If you need to manage numerous zones and records, a DNS system is a useful tool only if it meets the following criteria: it must be sufficiently robust and powerful to handle growth, and must allow for failover.
