It's not really that hard; I accidentally ended up doing just that in a split DNS configuration a couple of years back. Wanted to black-hole mail.yahoo.com, but didn't do it right. Ended up black-holing all of yahoo.com, and a lot of our billable hours was based on Web research. What did our consultants most often use to search? You guessed it...Yahoo! Obviously, this was *NOT* good....yeah, just mangle aol's DNS. Who knows how to do this ? Fixing this with tc is not that simple, as I don't know what to match.
Hmmm...this looks pretty keen. Worthy of investigation when I get some time.> > BTW, what's tc? tc is the Linux Traffic Control method. The `tc` executable inserts queuing disciplines into the kernel "insmod-style".
