I’m betting that not all of the WWW addresses go to the same ASN.
Perhaps you have noticed in your vast travels that domain names' significance is generally read right to left not left to right like IP addresses?
Sure, but I’m betting that trying to aggregate routing around COM. would be just as tricky as trying to aggregate it around WWW.
P.S. My prediction?
The world's major telcos et al, having had enough of various problems, from address exhaustion to non-stop security disasters, and the chaotic responses, propose and begin implementing an alternative. And that won't be through the IETF or similar.
I tend to doubt it. While I don’t discount what you say about telcos below, the thing to remember is that insisted that VOIP would never displace TDM in the average enterprise. When was the last time you saw a business phone system using TDM and not IP phones? Owen
