How > does centralizing the service help resolve a conflict correctly? Via several options: 1. First and foremost, those naming conventions 2. Reserved MAC address for blocks of the IP subnet 3. Historical MAC address assignment of the name/IP 4. Digital signatures of the client (both BIND 9 and reverse engineered ADS-DNS) These is just some of many approaches that can _only_ be accomplished in an unified layer 2 + layer 3 server. -- Bryan J.
