Accurately Check IP Reputation History

Millions of the internet’s most popular sites use IP reputation to detect bots, block email SPAM, prevent fake registrations, and verify users or payments. IP Reputation is so important, that it can cause your company’s email to automatically go to the spam folder, prevent purchases online, or even block your login to Netflix or Hulu.

IP address reputation is based on the neighborhood of your IP address, such as if it’s registered to a data center, hosting provider, or a residential or wireless network. Some services outright block entire neighborhood’s of IP addresses if their reputation is poor or if many IPs within that subnet are frequently engaging in suspicious behavior.

IP reputation history also plays a major factor in the IP’s current risk score. Proxy & VPN IP addresses or any that allow anonymized connections to be tunneled through their network can invite bad actors such as cybercriminals or fraudsters. These users tend to abuse IP addresses by committing fraud or abusive behavior. IP reputation services monitor abuse reports and online behavior to identify which IPs should be blacklisted.
