This article provides you with information regarding IP blacklisting.
The Definition of IP blacklisting
Blacklisting happens for any number of reasons, most typically when an IP address is suspected of sending spam. Continual blacklisting will affect your IP reputation because your IP address will be identified as a regular source of spam. Owners of an IP are responsible for what comes out of that IP address, so it’s important to stop spam from originating to avoid a reputation for spammy behavior.There are hundreds of blacklists out there, so if you’re wondering “Who is blacklisting my IP?” you will need to do some research.
Who is blacklisting my IP?
Domain Name System Blacklists, also known as DNSBL's or DNS Blacklists, are spam blocking lists that allow hosts's and administrators to block messages from specific systems that have a history of sending spam. As their name implies, the lists are based on the Internet's Domain Name System, which converts complicated, numerical IP address such as 126.96.36.199 into domain names like example.net, making the lists much easier to read, use, and search. If the maintainer of a DNS Blacklist has in the past received spam of any kind from a specific domain name, that server would be "blacklisted" and all messages sent from it would be either flagged or rejected from all sites that use that specific list.
