I would like to check the list of ip addresses and see if they are blacklisted (which would make me block them on my server).
What recommended websites offer this service?
We created a bash script to check the domain or IP address. It is very easy to use and available on GitHub.

https://www.projecthoneypot.org/ and
https://developers.google.com/safe-browsing/ (this file is provided by Google and is used by Chrome to check for malicious web hosts)
To check the list of IP addresses in the black list or not, use the "whoisthisip blacklist check tool .

There are many services on the network. I can say that MxtoolBox is an option for you.
If you are looking for a standalone application, you may depend on the IpBlacklist Checker. http://www.webtoolsin.com/products-1-ip-blacklist-checker.html
