IP Blacklist Check
Check a public IPv4 address against SpamCop’s email blocklist.
This tool checks one source: SpamCop SCBL. A result applies only to that list at the time of the check. It is not a complete security assessment, and an unlisted address is not necessarily safe.
SpamCop lists addresses associated with reported email activity. Listings can be mistaken or change quickly. Read the source’s guidance before making a decision. IPv6 checks are currently unsupported by this tool.
