Whether it *needs* to do a DNS or not is beside the point. The
conclusion is that it appears to be doing a DNS lookup. Could be for
nothing more than an IP address of the local machine.

How responsive is "nslookup"? Well, just because it looks something up
fast is no good measure, but if you can find something it might lookup
slow that should be fast then you've found a clue. How fast does it
lookup your oT machine and the others on the local net?

Wonder if your DNS servers don't know oT and are not authoratative for 
oT's domain so they go looking upstream DNS servers rather than return 
an instant "Not Found". As you say in an earlier message o8.com is a 
non-existent domain. So such a lookup has to go all the way to the root 
domain servers before that is discovered.
