Absolutely! Since you're currently running BIND 8, I don't expect you to be using many advanced features, and hopefully you have a fairly standard configuration. > 2- If step#1 is possible, as a minimum (H/W, S/W) what do I need for a > complete DNS/BIND system satisfying all the city's DNS needs > (internal/external resolutions). Depends, how long is a piece of string? I don't know what amount of traffic you're currently seeing, or what your uptime requirements are. > Any architectural/implementation/best practices advice would be highly > appreciated. Estimate what amount of traffic you're seeing during prime time. How many queries per second? I'd normally not recommend running BIND on slower multi-threaded Sun/Oracle servers like the T-series, you'll normally be better off with fewer threads but higher clock speeds from typical Intel/AMD systems. (caveat: I haven't benchmarked BIND 9.9.x, which might have improved this).
