Can someone explain the following dig results? The first dig @8.8.8.8 provides the expected result<BR>
<BR>
<BR>
: dig +noall +answer google-public-dns-a.google.com @8.8.8.8<BR>google-public-dns-a.google.com. 85040 IN A 8.8.8.8<BR><BR>
We get the same result from KLOTH.NET (<A href="http://www.kloth.net/services/nslookup.php">http://www.kloth.net/services/nslookup.php</A>)<BR>
<BR>
<BR>
But when we specify the public facing exacttarget.com server<BR>
<BR>
: dig +noall +answer google-public-dns-a.google.com @66.231.91.222 <BR>
<BR>
No answer<BR>
<BR>
And when we use +trace ... it seems to find it's way to the correct answer.<BR>
