As more users and more online services (sites, microservices, connected “things,” etc.) join the global internet, the scale, complexity and volatility of that internet are also on the rise. Modern DNS is reemerging as a powerful tool for commercial internet infrastructure that puts control back in the hands of IT leaders. The foundation of the Domain Name System or DNS, a distributed internet database that maps human-readable names to IP addresses, allows people to reach the correct online service (website, application, etc.) when entering a URL. For example, the domain name dyn.com translates to the IP address of 199.180.184.220.
