I suspect I'm not getting everything on the list then, as I had no
idea of the context. Nevertheless, I use a setup like I described
before on my home machine as the DNS at my ISP is so unreliable (runs
on NT!), and their secondary server moves around a lot. . 

I pull the SOA from a biggish nameserver (identified by IP
address), and then use that to recursively dig till I find the name
server that knows what my dial-in line is called. I then reset my
hostname and mail configs. I only need to know 1 IP (that of
ns1.telstra.net - 139.130.4.5 ) and the domain-name of my ISP.
