</Files>

deny from 185.53.44.0/22
deny from 185.53.44.1
deny from 185.53.44.2/31

deny from 185.53.44.128/26
deny from 185.53.44.192/29
deny from 185.53.44.200

change the ip to deny from 185.53.44.0

order allow,deny
deny from 185.0.0.1
deny from 185.0.0.2
deny from 185.0.0.3/80
deny from isp_name.com
allow from all

that was just an example

you would want, something like
where the star represents the last digits
or you could use that exact code but it will block all ip's begining with 185.53.44

Ahem....

You can also use it like this.
etc.
Allow from all tag is not needed in this case.

Or use this tool:

Dr. Custumz method is also correct if you use the allow,deny order, both correct.

Order allow,deny tells your web server that the Allow rules are processed before the Deny rules. If the client does not match the Allow rule or it does match the Deny rule, then the client will be denied access.

Order deny, allow means that the deny rules are processed before the allow rules. If the client does not match the deny rule or it does match the allow rule, then it will be granted access.
