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.)
