Blacklist Check

Right here and now you can check to see if your IP address is listed on an anti-spam database. Will your emails or forum chats get blocked? Below is a list of the major databases that track blacklisted IP addresses — look at the list now and you'll see there are no checkmarks next to the database names.

Check Your IP Address. Your IP address has been auto-filled in the box below. Click the "blacklist check" next to it and you'll then see checkmarks on the list. Read "What is this all about?" below for an explanation.

What is this all about?

This list above is of 50 DNS-based anti-spam databases. (DNS stands for Domain Name System, not for Do Not Solicit.) Most Internet service providers (ISPs) and web servers look to these lists for IP addresses linked to computers that send out spam or unwanted activity.

Your IP address might have resulted in the blacklisted symbol (IP Listed: Bad) appearing next to a few databases. It may be that at one point your IP address was flagged for some reason and blocked by some servers. (It could be that someone who was once assigned that IP address was blacklisted.)

Of course, if it 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.
