http://www.bind9.net/manual/bind/9.3.2/Bv9ARM.ch02.html#id2547108 How many domains (zones) do you currently serve? Do you want live zone changes without having to restart your DNS daemon? Are you and ISP or other (smaller) org? Do host only static zones or do you also host dynamic updates (like dyndns.org)? Do you host DNSSEC signed zones? If you're simply hosting static zones, even 250,000+ zones, a single dual core 2GHz machine with 4GB ram and a single 10k RPM SAS disk would be overkill. Serving DNS doesn't require a very powerful machine unless you're hosting millions of domains or doing DNSSEC. If you use something like PowerDNS instead of Bind, you can get by with even lower end hardware (memory) as it uses a database backend instead of static text files. This is great as you can do live changes via a web interface if you wish (this is something you have to build from FOSS components--it's not part of PowerDNS). This thread, while very old, is educational.
