Need relief for your DNS headaches? First, it helps to understand how the domain name system works under the hood.

DNS is the Internet’s phonebook. Whenever you type in or click a human-readable web link (such as hpe.com), your web browser calls on a domain name system (DNS) resolver to resolve its corresponding Internet Protocol (IP) address.

DNS is essential. Without it, there is no Internet. Period. End of statement.
