What is DNSSEC and Why Should Anyone Care

First, we need to understand what DNS (Domain Name System) really is and how it works. In short it is a naming method for computers, services, and other resources connecting to the internet or one’s private network. The purpose of DNS is to translate a domain name for example a website’s name such a www.somedomain.com into an ip address. People would not want to memorize an ip address every time they wished to access a particular website. DNS (Domain Name System) provides a worldwide convention of mapping these names to a specific server’s IP Address and has been doing this since its infancy of 1985. Domain Administrators may create CNAME records to map subdomains to the same server as the root domain with a different path or to an entirely different ip at another server anywhere in the world. To keep the internet organized there are two namespaces in place which are: domain name hierarchy and the ip address spaces.

Taking a very basic look at this the request starts at your stub resolver in your computer after which intern requests for more information from a more advanced DNS (Domain Name Server). Next the resolution process sends recursive calls to multiple authoritative name servers to store the DNS information within its database. The name servers not only have to direct web traffic but also several other types of traffic such a MX records to mail server, etc. The DNS (Domain Name Server) is then translated and sent to the respective server after first checking what type of traffic it is respectively. Keep in mind that it may have to go through yet another translation if there is subdomain and then rerouted within that server or to a server anywhere else in the world.
