The cumulative merchant losses due to online fraud are projected to exceed $343 billion by 2023, according to Juniper Research. To reduce the chances of fraud, businesses must take multiple measures to protect their website and email communication. IP reputation checkers are one of those tools, helping companies identify and mitigate security issues before they become costly problems.

IP Score Lookup: Understanding the Reliability of an IP Address

The best IP score lookup tools will also help you minimize phishing attacks, spamming and spoofing, which are common tactics of cybercriminals. These tools will provide you with an overall rating based on several pre-determined components, such as whether the IP is on a blacklist or if suspicious ports are open. Some tools, such as the free reputation checker from Cisco Talos, will provide you with information about specific blacklists an IP is listed on. Other tools, such as MultiRBL, will check the reputation of an IP address against more than 200 mail server blacklists. They also provide additional data such as country, operator, and proxy status, and offer both manual and API searches.

Other services, such as IPQualityScore, offer a full suite of reputation tools including blacklist checks and more advanced cybersecurity features such as dark web monitoring, bot mitigation and detection, chargeback fraud prevention and more. They also offer a robust API for those interested in integrating their services into their existing software stacks. The tool supports both IPv4 and IPv6 addresses and provides geolocation, ISP info, open ports, risk analysis and more.
