It’s always annoying to me, being a convert from *BSD to Linux, that tools lke dig and host aren’t in the minimal base install.  I realise that this makes me somewhat of a hypocrite, as I prefer an additive system rather than a subtractive base OS.  Nevertheless, I’m continually surprised that “host” isn’t available after installing a minimal CentOS system without adding an additional package.  So, since I always forget, here is a quick blog post to remind me and any other converts how to install those tools:

 yum -y install bind-utils

That’s it.  Tragedy avoided.  Now I can make sure my AAAA records are working.
