DNS setup to resolve domain.com

[michael23]

How do the DNS records need to be setup to resolve the host
"domain.com"?
I have www.domain.com working just spiffy...
but I'd like to allow people to type "domain.com" into their browser's
location bar and still find my server
My first attempt was to leave the host name blank in the "domain.db" and
"192.168.1.1.db" record files, but that didn't work.
Any ideas?

Thanks,
