An IP block list is a database that stores records for a specific IP address. It’s intended to help security software block communications from bad IP addresses.

What happens if my IP is blacklisted?

There are hundreds of blocklists on the Internet. Each one has a different set of criteria for requesting removal of a particular address. Some blocklists rely on a few basic elements, such as a spam score or a technical violation, while others rely on evidence. Regardless of the criteria for inclusion, it’s worth doing your research to determine the best practices for removing an IP from a blocklist.

A few of the most popular ways to get an IP on a block list are through compromised accounts and poor email practices. Other ways include spambots, infected devices, or botnets. Whether or not an IP gets on a list, it’s important to take action as soon as possible.

Using a service to check if an IP is on a block list can be a good first step. However, if you find that your IP has been blocked, you’ll need to contact the blacklist in question directly to request its removal. While the process may seem simple, it can be time-consuming.

Another way to know if your IP is on a block list is to check the number of spam complaints you receive. If you see a large number of complaints, there’s a good chance that your IP is on a list.

There are also some websites that can tell you if your domain has been listed on a whitelist. If the IP is not on a block list, it’s still a good idea to add it to your Do Not Block list for a particular service.
