- I'm afraid the naive reasoning is on my part. You are of course correct. The
- fact that DNS is a distributed database escaped my attention for a moment.
-
- Using a centralised database would not cause any problems, but the fact
- that queries can be answered by a remote DNS means that VCI/VPI pairs are useless
- except to hosts local to an ATM network and DNS domain.
