The domain Name system or the DNS was strated in the year of 1984 by the ARPAnet and the Internet Network Information Center (INTERNIC) based in Virginia managed it .now it is taking cared by the ICANN, the non-profit corporation that oversees the DNS. The DNS has created a huge impact on the internet users and it is also user friendly because it uses the name and simple English to identify server computers,e-mail addresses and individual files.for an example many websites to be identified by their IP addresses ,Finding what you want to find on the ‘INTERNET (and advertising on the ‘INTERNET) would be a very difficult proposition without the DNS.
DNS management software is an computer software that has the complete control over the Domain Name System (DNS) server clusters and its main purpose is to reduce the human error while editing complex and repetitive text-based DNS server configuration files because such files are often deployed on multiple physical servers.The DNS service providers oftenly deploy a complex mixture of different types of DNS servers in their networking,In addition to it the diiferent zone resource records must be provided to the DNS clients based on the clients IP address (usually similar to a geographical location ).The only practical way to overcome such crucial internet infrastructure it to rely on databases and complex DNS management software to insure homogeneity and avoid single points of deployment errors.
Before the availablity of the domain Name system management software, lots of large DNS service providers relied on system administrators and the in-house custom collections of Perl or Shell program scripts that provided some automation for managing large sets of DNS zones across a cluster of servers.some of the domain Name system management softwares includes high level management tools .The most widely used DNS software across the world is the Internet Systems Consortium (ISC) BIND DNS server software does not contain high level (server cluster) management software.
The below are managing resource records
After you create a zone, additional resource records need to be added to it. The most common resource records (RRs) to be added are:
1) Host (A) is nothing but a records. Mainly, it is used for mapping a DNS domain name to an IP address used by a computer.
2) Alias (CNAME) For mapping an alias DNS domain name to another primary or canonical name.
3) Mail Exchanger (MX) For mapping a DNS domain name to the name of a computer that exchanges or forwards mail.
4) Pointer (PTR) For mapping a reverse DNS domain name based on the IP address of a computer that points to the forward DNS domain name of that computer.
5) Service location (SRV) For mapping a DNS domain name to a specified list of DNS host computers that offer a specific type of service, such as Active Directory domain controllers. Other resource records as needed. For more informatio Visit:Register domain name
