How to install newer version of /usr/bin/host via Homebrew?
The folder /usr/bin/ is Apple's realm and protected by SIP. You have to wait until Apple provides an updated version of host.

AFAIK Homebrew doesn't provide a newer (or better: any) host executable.

So either use dig: dig &lt;host&gt; type257 or install go and dnscaa - CAA DNS Library for Go.
