8. Filtering by IP network

 

If you want to blacklist or whitelist specific IP network, select the appropriate filter and input one or more subnets and specify a rule (Blacklist or Whitelist). As a result, records will be added to the table.

Subnet blocking:

1.2.3.4 - IP address

/16 - subnet mask

If you don't know how it works simply put numbers for mask divisible by 8:

  • 1.2.3.4/8 - all IP addresses starting from 1.n.n.n (from 1.0.0.0 to 1.255.255.255) will be blocked.
  • 1.2.3.4/16 - all IP addresses starting from 1.2.n.n (from 1.2.0.0 to 1.2.255.255) will be blocked.
  • 1.2.3.4/24 - all IP addresses starting from 1.2.3.n (from 1.2.3.0 to 1.2.3.255) will be blocked.

10. Go to the plugin settings in your website dashboard and save settings

 

It is essential for changes to take effect even if you haven't change the settings. If you don't do this, changes will take effect only in 24 hours.

 

 

Note 1: If you want to block any IP/email and block access to comments/register, just go to Cleantalk Dashboard —> Log, find the necessary request and mark it as "Spam". This IP/email will be added to your personal blacklist.

 

More details are here: [ https://cleantalk.org/faq#feedback_spam ].

 

Note 2: You can use masks when specifying filters. Symbol asterisk "*" means any set of characters. *@mail.com - will block any address ending by @mail.com

 Examples:

  • name*@example.com (all e-mail addresses with any set of characters after "name" will be blocked).

  • *aa44@example.com (all e-mail addresses with any set of characters before "aa44" will be blocked).

  • *kkk*vvv*@example.com (all e-mail addresses with any set of characters before "kkk", before "vvv" and after "vvv" will be blocked).

 • *@*example* (all addresses with any set of characters before and after "example" in domain name will be blocked).

  • And so on, you can use any combinations of characters and asterisks to make a mask.
