What is an IP blacklist?

An IP blacklist (DNSBL) is a public database of addresses that have been reported for sending spam, running malware or other abuse. Mail servers and websites query these lists in real time to decide whether to trust a connection.

Why is my IP address on a blacklist?

The most common causes: a device on your network is infected and sending spam, your mail server is misconfigured (open relay), or your address sits in a range that was previously abused by someone else. Dynamic home IPs are frequently listed simply because of their history.

How do I get my IP removed from a blacklist?

First fix the underlying cause (remove malware, secure the mail server, stop abusive traffic). Then use the removal or delisting page of the specific blacklist — each result in the table links to it. Most lists delist automatically once the abuse stops and a waiting period passes.
