A Remote Black List is a collection of suspicious IP addresses held on a third party server. These could be due to spamming activity, invalid login attempts, misbehaving bots, or any other significant security infringement.
What Happens If Your IP Address is Black Listed
If you find your IP address on a blacklist, don’t panic! Due to their nature, IP addresses change all the time and it’s probably just your bad luck that you got one that has been tainted. As a result, you may not have access to sites that check these remote blacklists before allowing visitors.
