Help scripting dns lookup using awk

[Jonathan McKeown]

Ernie, I've been following your questions over the last month or so. I
think I can guess your problem domain, and I suspect if you told the list
what you're trying to achieve you'd get much better suggested solutions.

As it is I think you have one approach in mind, and all your questions
relate to implementing parts of your idea.

My humble apologies if I'm wrong; but please consider explaining what the
overall problem is. (Someone mentioned x-y problems - I think you have one
here.)
