My host command doesn't understand CAA records.

host -t CAA google.com
host: invalid type: CAA

which host

how to install newer version of /usr/bin/host via Homebrew? In which package the host command?

1 Answer 1


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 <host> type257 or install go and dnscaa - CAA DNS Library for Go.

  • can you describe how to install new dig? dig also doesn’t support CAA inheritance, and the output of the query is the binary-encoded record (although in newer versions of dig, support for parsing the record data is present)

    @FyodorGlebov It's the same with dig: there's no dig receipt for brew. If you need caa inheritance you have to install go & dnscaa.
