What kind of a box would be sufficient to serve about ten thousand DNS entries (not including subdomains)?

We have an empty box:
- IDE
- Dual P3 1.2GHz
- 2 Gb RAM DIMM

Would that be ok or shall we get a scsi bix?

That box is fine. If you are using the Buggy Internet Name Daemon then it will serve DNS out of memory anyways.

If you use djbdns you will serve DNS from disk but performance will be just fine. :-)

Thanx, David. Thats what our sysadmin keeps telling me. I just like spending company money :))

As davidu posted above - you will be fine, unless you:

1.) Provide DNS service to hundreds dial-up and DSL users (recursive DNS lookups, like an ISP)
2.) if you force a small TTL value for high number of zones
3.) dynamic DNS also takes a bit more resources..
4.) TSIG and DNSSECURE (correct me if I didn't type correctly) has a bit higher HW resource requirements for zone transfers

.. it also depends from the zones you are hosting. You will be not able to host 10,000 of zones, for example, yahoo.com, usbank.com, ford.com, microsoft.com etc..

ps. I don't think you need a SCSI disk system for DNS server.
