Allow and Deny
The Allow and Deny directives let you allow and deny access based on the host name, or host address, of the machine requesting a document. The directive goes hand-in-hand with these is the Order directive, which tells Apache in which order to apply the filters.

The usage of these directives is:

allow from address

where address is an IP address (or a partial IP address) or a fully qualified domain name (or a partial domain name); you may provide multiple addresses or domain names, if desired.

For example, if you have someone spamming your message board, and you want to keep them out, you could do the following:

deny from 11.22.33.44

Visitors coming from that address will not be able to see the content behind this directive. If, instead, you have a machine name, rather than an IP address, you can use that.

deny from hostname.example.com

And, if you'd like to block access from an entire domain, or even from an entire tld (top level domain, such as .com or .gov) you can specify just part of an address or domain name:

deny from 192.101.205
deny from exampleone.com exampletwo.com
deny from tld

Using Order will let you be sure that you are actually restricting things to the group that you want to let in, by combining a deny and an allow directive:

Order Deny,Allow
Deny from all
Allow from hostname.example.com

Listing just the allow directive would not do what you want, because it will let users from that host in, in addition to letting everyone in. What you want is to let in only users from that host.
