If your blacklist lookup IP address, it can be difficult to send emails or use some websites. That’s because blacklisted IP addresses are flagged by email servers as potentially spammy and not trusted, and this makes it more likely that the emails sent from those IP addresses will end up in recipients’ Spam folders. In other cases, the web hosting or server provider will block access to a website when an email is sent from one of those IP addresses.
There are several ways to check your IP address to see if it’s on any blacklists. You can try using a dedicated online service, a network security tool or command-line tools. If your organization uses a hosted mail system, you can also ask them to look up your IP. Another option is to subscribe to a service that monitors 130+ blacklists for you.
Blacklist Lookup for IP Addresses: How to Keep Your Network Safe
Getting your IP address removed from a blacklist can be tricky. It depends on how your IP address ended up on the list in the first place and what steps you take to resolve any issues identified by other parties. Typically, you can get your IP address off the list after determining that there is no infection on your network and resolving any malware-related issues. It may take longer if you’ve been a persistent offender or if you’re associated with a certain type of activity, such as facilitating file sharing without copyright or cyberbullying.
Some blacklists have a self-service removal feature that lets you remove your IP address from the list without much trouble. This is a good option, but make sure that you’ve fixed any issues before trying this. Otherwise, if you get listed again, it won’t be as easy to have your IP address removed the next time around.
