Step 6 – Choose what blacklists to use

You are here:

The paid plans let choose which blacklists to use in the lookups to perform with the API. Depending on the type of lookup (IP, Domain or Email) it’s possible to select the set of individual blacklists to include. To configure these lists, select BLACKLISTS in the left side menu option. left menu blocklist


Once inside the Blacklist page, the user can choose among all the lists corresponding to IP, Domains, and E-mails. To activate or deactivate a list the user can use the switch at the left side of each element of the list or can use the Advanced Search feature.

Warning: By default, all lists are enabled after the registration process. We strongly recommend enabling only the lists needed to avoid False Positives.




Each of the lists contains a list of different IP addresses, Domains or Emails depending on the type of content to block. To find out what each list does, the user can click on its name to see full detail information to the right about what kind of list is and how can help the user.




The information shown in the list details is:

  • Name.
  • Description.
  • Why the user should use this list.
  • Source site: URL of the site the list is downloaded.
  • Items: Current number of items.
  • Updated: How often is the list updated.
  • Last update: Last time the list was updated.
  • Visibility: If this list is visible to all users or only to the user.
  • Tags: Helper taxonomy to classify what kind of content has the list.
  • Sensitivity: A list can contain IP addresses, domains or emails that can be more or less dangerous. An element with a sensitivity closer to ‘1’ means that it is more dangerous than a sensitivity closer to ’10’ which normally means that the element is not very risky or for informative purposes only. As a rule of thumb, we recommend to start always with lists with ‘1’ sensitivity and include later on other lists.




To select the right blacklists according to the requirements of the user there is an Advanced Search feature that let the user choose them according to sensitivity and taxonomies criteria combined. Clicking on Enable Advanced Search will show the different filters and then it will disable all the blacklists below. Clicking on Reload it will disable the advance search and will also reload the old values stored by the user.

The user now should choose the right value for the sensitivity and the tags to include in the filter. Both can be combined to select the right blacklists. Once the blacklists have been selected the user has to click on Save to store the new blacklists in the database. The new filters will be applied immediately in all the different API servers.

For example, if the user wants to blacklist all the different TOR IP addresses, she should select:

  • Sensitivity 1 (all TOR blacklists have the sensitivity to ‘1’, so there is no big impact on this.
  • Tags: The tag ‘Tor’ should be enough.


The blacklists related to Tor IP addresses will be selected. Now, the user should click on Save to accept this change.
