HELL! THANKS DUDE! Thats the solution for me! Its ugly, but i live in an
ugly network, so its perfect :) ! And however, once implemented its
centraly administered. i tested and implemted it quick and works fine now.

btw: "Name Resolution Spoofing" is the right name for that :)

I assume using "view" feature is something called "split brained" earlier?!
however, no topic to me since i dont serve to the internet. but thanks
anyway!

hmmm.. ur right. but i thought i would act less "aggressive" to the internet
if i use the NS at my ISP to make use of its cache and other stuff rather
than making direkt load to the root servers. of course some  of my request
will go up to the top even i use my ISPs NS as forwarder. but wont it save
traffic load?   am i wrong?

AGAIN, THANKS FER YER QUICK HELP!!
