On Debian, the canonical tool for performing generic hostname lookups according to the rules established by /etc/nsswitch.conf and other local system config files would be: getent hosts NAME unicorn:~$ getent hosts www.google.com. 2607:f8b0:4009:80b::2004 www.google.com unicorn:~$ host www.google.com www.google.com has address 142.250.190.100 www.google.com has IPv6 address 2607:f8b0:4009:80b::2004 (Demonstrating the difference between canonical and useful. My system has no IPv6 capability.)
