| True, but I never have figured out what the argument to dig should look
| like to do anything useful.  host is simple.

If host(1) does what you want, it would be crazy to use dig.

Dig's output is a barely digested DNS response.  You need to
understand the sections of the response (Question, Answer, Authority,
Additional).  You need to know that the absence of an Answer section
is meaningful.  You need to find the relevant information buried in
the avalanche.

You need to know that if you don't specify the type of query, if there
is any cached entry (of any type), it will only give you what is in
the cache.

I do use dig for figuring what's up with DNS.  It has lots of controls
and it doesn't hide anything from you.  To a fault.
