Why is my home IP on a blacklist?

Home addresses usually land on lists because something used them to send spam or attack traffic: a malware infection, a compromised router, a misconfigured mail server, or simply because the whole ISP range has a bad reputation. Delisting is normally automatic once the offending behaviour stops.

Does being blacklisted affect anything besides email?

Blacklists matter most for email deliverability, but the same reputation databases feed fraud screening, so a listed IP can also face more CAPTCHAs, blocked signups and stricter checks on websites and APIs.

How do I get my IP removed from a blacklist?

First stop the cause — close the open relay, clean the infected device, secure the router. Then use the blacklist's own lookup/removal page (each one has a form): some delist automatically within hours or days of clean traffic, others take removal requests. Spamhaus intentionally does not accept requests for dynamic ranges.

Can a blacklist listing be wrong?

Yes. Listings are probabilistic and ranges are shared: on CGNAT or shared hosting, other people's behaviour on the same IP can list you. Check which list flagged you, follow its evidence, and appeal through its removal process — reputable lists correct genuine false positives.
