dns entry for top domain name

[John]

Hi,

I'm trying to figure out what would be the correct entry in the db
file so i can resolve a top domain..

ie..i want to resolve

foo.com


what would i need to have in the file?

i tried.

*   in a 192.168.1.2
foo.com. in a 192.168.1.2



and that didnt seem to work for foo.com...it works to resolve
<everything>.foo.com

but what's the line i need to resolve foo.com itself?

thanx
