Training for Networking Professional DNS Infrastructure

The Domain Name System (DNS) infrastructure consists of DNS servers that run the DNS Server service and DNS clients that run the DNS Client service.

DNS is a system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks, such as the Internet, to locate computers and services with user-friendly names. When a user enters a DNS name in an application, DNS services can resolve the name to other information that is associated with the name, such as an IP address.
