	My point is that you're doing it correctly.  If you lose
one of your aggregate blocks, it's not going to cause a problem.  Like
for example, if someone else started to announce your /24 or a /19
with your dns servers in it.

	You also distribute nameservers geographically, so if you
lose power in a location, you don't die.
