There are many spam advisory databases on the Internet, such as spamhaus and so on.

For example, to query whether IP 1.2.3.4 is blacklisted by ahbl.org, use the following command

Nslookup 4.3.2.1.dnsbl.ahbl.org

If the returned result is Non-existent domain, there is no problem.

If the return result is 127.0.0.x, it means that it is blacklisted, and x can be a value of 1-255, depending on the database.

Of course, some databases provide web query, which is also very convenient.

The advantage of viewing with commands is that you can write scripts to view multiple databases at the same time.
