Blacklist Lookup is a SEO Tool used by website owners, webmasters or even Search Engine Optimization professionals, to check if a domain is blacklisted or not.
Reasons why your IP could end up being listed.
- Virus, Malware, or spam.
- If you've got a virus or malware and your computer is constantly pinging or attempting to communicate with other computers, you are bound to hit a computer where the admin will see your attacks, block your IP address and then report it accordingly.
- If you send spam or run a mail server that is not properly configured and it allows spam to be sent, that IP address may get blacklisted.
- If you have a DHCP IP address and you're not a spammer and don't have a virus, it's possible that the person who had your IP address before you was, or the person who had it before them, and so forth and so on.
Having a blacklisted Domain or IP Address doesn't necessarily mean that you are to blame. You may be completely innocent.
What is for sure is that only the Internet Service Provider (ISP) knows who had the IP address prior to assigning it to you. On your part, just make sure that you don't send any spam or viruses to nobody.
