Over a thousand machines at my employer and each run a local bind daemon with a forwarding configuration to our top level servers. We tried switching from that to a centralized DNS server but there were problems with centralization and we switched back to having a local named. BIND is designed to be distributed and works well that way. There are many reasons to run a caching name server. Here are a couple. If you have a large network of machines then local caching reduces the network traffic. Local caching reduces the named load on the infrastructure servers. The bigger the network the more important it is to run a caching name daemon. Some sites are very large. If you have a slow network connection then a local bind improves performance by local caching. The slower the connection the more important it is to run a caching name daemon. Phone lines are slow. Most users small sites exist behind phone lines. Running a local caching name server daemon is a very, very popular configuration. Bob
