BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library and tools for verifying that the DNS server is operating properly. However, bind is not installed by default including the dig command.

You must install bind-utils package on CentOS 8. It contains a collection of utilities (such as dig command and other) for querying DNS name servers to find out information about internet hosts. These tools will provide you with the IP addresses for given host names, as well as other information about registered domains and network addresses.
