Domain Name System Components. DNS consists of the following components. You have your Subdomain or Third Level Domain then you have your Second-Level Domains which is followed by a Top-Level Domain.
It is made up of three parts. Each node or leaf in the tree has a label and zero or more resource records RR which hold information associated with the domain name. The right-most label conveys the top-level domain.
The second is a Globally Distributed Database implemented on a network of Name Servers.
When youre navigating to any website address or URL you will also come across the Protocol which occurs before the subdomain. Flags are an integer which indicates how a CA should handle tags it doesnt understand. Generic Domains It defines the registered hosts according to their generic behavior. There are three main parts to any domain name.
