The sheer volume of resources available on the Internet and enterprise networks is astounding. Trying to remember the IP addresses of even a fraction of these resources would be quite difficult. However, we can assign names to these resources and use the Domain Name System to translate easy to remember names into their specific IP addresses. In this course, you'll learn about the organizations that coordinate the global DNS. We will focus on the organization and structure of the DNS namespace, the types of top level domains, the purpose of the root name servers and primary and secondary name servers, the DNS name resolution process, and the DNS message format. You will also learn to match the abbreviations with the resource record function when given a list of resource record abbreviations, the advantages of DDNS, and finally, you'll be introduced to DNS troubleshooting tools.
