"The Domain Name and Addressing System (DNS) is a critical component of the Internet infrastructure. The DNS associates user-friendly domain names (e.g., www.commerce.gov) with the numeric network addresses (e.g., 170.110.225.163) required to deliver information on the Internet, making the Internet easier for the public to navigate. The accuracy, integrity, and availability of the data supplied by the DNS are essential to the operation of any system or service that uses the Internet. Over the years, vulnerabilities have been identified in the DNS protocol that threaten the authenticity and integrity of the DNS data. Many of these vulnerabilities are mitigated by DNSSEC, which is a suite of Internet Engineering Task Force (IETF) specifications for securing information provided by the DNS."
