If you are looking to specifically answer that as a, b, c, or d I am
not certain.  I'm sure you know you can ping the site and get it's IP.
 That IP would come from the DNS records.  Beyond that I can't help
you.  I did do some theory with named and configuring a secondary DNS
some while back.  But it was a one time thing and not sufficient for
me to absorb much of it seeing it's not something I deal with on a
daily basis.
