I don't want to seem overly picky, but to avoid questions like
"what if the second one gives different information from the first"?
you should say that it checks them in order, not checks both of them.

Now I'll be picky.   ;-) ;-) ;-)
You should say "to attempt to find the host", because
it may still not find it.  Assuming it is a host you're looking
for, that is an "A" record rather than a "PTR", "COA", "TXT"
or other resource record.   You might be able to find one but
not the other, for example a MX record but not an A record.
I often see 'incomplete' DNS entries.   :-(
