IP Address Lookup Tool

  We strive to keep as much spam email as possible from reaching our email users through a variety of security measures. Sometimes, legitimate email is blocked or “blacklisted” when large amounts of spam are detected from an IP address. The owner of the blacklisted IP address must take action to fix risky behavior occurring in their systems so that we can remove the block.

If you received a “bounce back” message, your email was flagged as coming from an IP address that has been blacklisted. While you may not have sent the spam, another user sharing the same IP address with you did, triggering the block.

This tool is provided to help determine if an IP address has been blocked due to potential spam, virus or phishing activity. This Lookup Tool is for IP addresses only. Do not enter email addresses or domains.

IP Address Lookup

It is likely that the owner of your IP is already aware of the block and is working to fix the problem. However, if you are unsure, feel free to contact your IP owner or email provider (often your Internet Service Provider) to ensure speedy resolution.

If your IP address has been blocked, you will be given the opportunity to submit a request for removal of the block by completing a Removal Request Form.
