There are several reasons to deny specific IP addresses or exclude URLs from your website. For example a traffic intensive Spider or to reduces grant access to an specific intranet host only. Just to point it out – I use the Adress 127.0.0.1 in this post for practice examples.
Lock out a specific IP address
order allow,deny allow from all deny from 127.0.0.1
The IP address obtained when the page is called a 403 (Not Authorized). All other access
Lock out multiple IP addresses
order allow,deny allow from all deny from 127.0.0.1 deny from 127.0.0.2 deny from 127.0.0.3
Just write ip addresses to be blocked to the file – line by line
To Lock out a range of IPs
order allow,deny allow from all deny from 127.0.0
All addresses correspond to this IP range excluded. In this case 127.0.0.1 to 127.0.0.255
Allow only specific IP addresses
order allow,deny deny from all allow from 127.0.0.1
As described in the Examples all settings work with “allow from” like it does with “deny from“.
