configure apache to accept request form specific IP

Hi,

What should I change in the httpd.conf so that the apache will accept request from page from specific IP and deny all the rest IP.

I am reading the document of the apache but it is very long (700 pages) and I searched but I could not find something about this.
So if someone can explain me how to do this specific thing, I will be glad?

The direction that I think about is:

<Directory / >
Order allow,deny
Allow from IP1,IP2
</Directory>

while IP1 and IP2 are replaced with the IP numbers that I want to allow.
However I want to make sure it will reject all other IP request.

Thanks in advance.
