How this IPs goes throught my htaccess?

Question

I have htaccess file like this:

<Limit GET HEAD POST>
order deny,allow
allow from xx.xx.xx.xx/xx
allow from xx.xx.xx.xx/xx
allow from xx.xx.xx.xx/xx
...doesn't matter....some ips...
deny from all
</Limit>

And this ip adressess in MYBB:

5.10.83.26
5.10.83.7
5.10.83.40

every day making my server overloaded, and than it is stucked, I have to wait for host to flush-hosts, I haven't permission...

How those ip adresses avoiding my restrictions in htaccess? -Yes, I am sure they are not allowed.

I use WordPress as root, and subfolder is MyBB. Those adresses I see in MyBB.

At least how can I add deny from 5.10.83.00/26 to htaccess and keep deny from all.
