Of course, if seems that you're involved in spamming or other unwanted online behavior, your IP address could get blacklisted and blocked. It will get flagged and land on one or more of these databases. You'll be able to see that here at any time by running a new blacklist check.

The following blacklists are offline and should not be used by any systems.

WhatIsMyIPAddress.com does not run, manage, or have any direct relationship with any blacklist. We provide a single location to check the status of an IP address on 3rd party blacklists. WhatIsMyIPAddress.com does not recommend the usage of any specific blacklist and does not condone blacklists that require payment for removal. Our inclusion of such blacklists are for the purposes of completeness and should not be considered support of that blacklist's usage.
