Block an IP address range

In this tutorial we will block an IP address range.

REQUIREMENTS

• Troll 6.x
• Drupal 6.x

STEPS

1. Navigate to admin/user/troll/ip_blacklist/import
2. Into the field List: type in the start of IP range to block.
   For example if you want to block 172.16.254.0 through 172.16.254.255 then type in 172.16.254.0/24
   This would block the 256 IP address locations.

   Notes:
   -The IP format must be *.*.*.*/24
   -Replace * by numbers. You must add /24 at the end. /24 is a CIDR notation. Read more

3. To view the full list of blacklisted IPs go to admin/user/troll/ip_blacklist/search
   Search for any IP within the range you just blocked. For example 172.16.254.50 without the quotes. If successful the IP shows as blacklisted.
