Host Reputation

Check the reputation of an IP address or domain against a comprehensive list of blacklists and blocklists (DNSBLs). We currently check 192 DNSBLs and 37 URI DNSBLs. This API can take anywhere from 5 seconds to 20 seconds to run depending on the current response times of the active DNSBLs. Please Note: you should not call this API repeatedly (or concurrently) in short periods of time or you may get blocked for list abuse.
