Understanding how to manage a DNS server is key for any IT professional, including DNS administrators and programmers, analysts, and CTOs. Managing DNS Essential Training covers the theory and practice of administering DNS using dig and other DNS server technologies. Heavy in practical examples, and full of excellent visualizations to help with absorbing concepts, this course will have you saying “Eureka, I’ve got it!” in no time!
