IP Reputation Checker
Blacklists for the address and who is behind it: a Tor exit node, a data center, a content delivery network or an ISP.
What reputation is built from
Websites and mail filters look at two things. The first one is blacklists: an address listed in Spamhaus SBL or XBL gets rejected by nearly every mail server, while a PBL listing on a home address is considered normal.
The second one is who stands behind the address. Sites with bot protection trust Tor exit nodes and data center addresses less than carrier addresses.
For a domain, the first address gets checked. To review every address of a site or mail server, use the IP blacklist check.
