This may be a little off topic, but, if anyone knows the answer, I am
sure they hang out here.
I have been through the archives and found a thread or two that touch on
this subject, however, some clarification would be good.
What I have been able to piece together is that the C root server
[192.33.4.12] is a BIND9 server and responds with a *referral* to my NS
query and the other roots are BIND8 and respond with *answers*. Am I on
the right track?
Thanks in advance,
Dave...
