Domains

Here you will find a list of available domains under the Available Domains box. Domains can be enabled or disabled by moving them from the right to the left box by selecting them and clicking on the single right or left arrow. All domains can also be enabled or disabled using double arrows.

Each of the domains keeps an updated list of blacklisted IP addresses.

You could use a preloaded domain list, but you could also add your custom domains. This can be achieved in the Domain Section you will find in the left main menu. Please, visit IPDS >> RBL >> Domains for further information.

Farms

In this section, you will find a list of the farms available. You could add or remove farms from the list using the arrow buttons.
