Blocking IP range help with .htaccess

[Alien]

Hi all,

Can anyone kindly assist me with creating an .htaccess file to block an IP range which is spamming several sites on my server?

I'm getting spam from an originating T-Mobile IP range of 178.100.0.0 - 178.103.255.255. T-Mobile won't do anything about it and never reply.

So, rather than use the WHM to blanket ban T-Mobile users with a wildcard on the entire server, I'd like to individually upload an .htaccess file to block several sites only.

How do I block the entire range as above?

e.g. Would this work?

order allow,deny
deny from 178.*.*.*.*
allow from all

Help gratefully received, thanks!

This should work:

order allow,deny
deny from 178.
allow from all

You can also block specific ISPs

If you really want to block the whole 178 range then the following would do it:

deny from 178.

Haha, great minds think alike.

Btw I don't think you are allowed affiliate links in your sig here.

Thanks guys, much appreciated.

I've uploaded my individually needed .htaccess files and will see what happens.
