codeman1234 · 12-06-2014, 04:02 PM

Hello,

I am trying to block class A Ip ranges on my server from 213.238.237.10 to 210.243.21.254 with htaccess and I am doing this the following way:

<Limit GET POST>
order allow,deny
allow from all
deny from 213.238.237.10 210.243.21.254
</Limit>

My question if is this correct or not? Since I dont find other way to block class a ip ranges with htaccess.

Thanks!

Hey jlinkels,

Thanks a lot, in case anyone has same issue this is explained bellow

Quote:

Valid IP Addresses

IP addresses are in the form xxx.xxx.xxx.xxx and each of these four numbers is from 0-255.
You can enter partial addresses to restrict larger blocks of addresses:
1.2.3.4 Blocks one specific IP address
1.2.3. Blocks IP address in the range 1.2.3.0 to 1.2.3.255 (ie.. 1.2.3.xxx)
1.2. Blocks IP address in the range 1.2.xxx.xxx
1.2 Blocks IP address in the range 1.2xx.

So for B Classes here is an example how to do it to block B Class IP 101.3.55.66:

RewriteEngine On

order allow,deny
deny from 103.3.
allow from all

Thanks again!! Just one last favor jlinkels can you just confirm me that I understand it correctly please?

This blocks 103.3.0.0 until 103.3.255.255. Not 101.3.55.66, but that might be a type. And addresses are nowadays classless, so the range is correct but it is not called class B anymore.
