example.com/net/org DNS records

Does anyone know why IANA has assigned NS and A records to the example.{com,org,net,...} domains? They even put up a website at the IP explaining RFC 2606. * Why did they assign NSs and a valid IP to these invalid domains? * Are they breaking the RFC by doing this? * Are they breaking anti-UCE filters by doing this? (yes) * Are they harvesting URLs and referrers? * Will they next advertise routes for RFC 1918 addresses? -- Roger Marquis Roble Systems Consulting http://www.roble.com/
