Blocking IP Addresses in Apache

A common question I see being asked on various lists is “How do I block an IP address from accessing my site?”

This should *not* be treated as a robust security measure, there are many ways this could be bypassed. Use at your own risk.

Copy and paste the text below into a file and name it .htaccess. Then upload it to your web server.

order deny,allow
deny from nnn.nnn.nnn.nnn

(replace nnn’s with the IP address you wish to deny)
