Why IP Reputation Matters
  • Protects your systems from known malicious actors
  • Helps identify potential security threats
  • Reduces the risk of data breaches and cyber attacks
  • Improves email deliverability by avoiding blacklisted IPs
Factors Affecting IP Reputation

How to Improve Your IP Reputation

If you discover that your IP address has a poor reputation, here are some steps you can take to improve it:

Best Practices for IP Reputation Management

  • Secure your systems: Ensure your servers, networks, and devices are protected against malware and unauthorized access.
  • Monitor outgoing traffic: Regularly check for unusual outgoing traffic that could indicate a compromise.
  • Implement email authentication: Use SPF, DKIM, and DMARC to prevent email spoofing.
  • Request delisting: If your IP has been blacklisted, contact the blacklist operators to request removal after addressing the issues.
  • Use dedicated IPs: For critical services, use dedicated IP addresses rather than shared ones.

Frequently Asked Questions

What is an IP abuse score?

An IP abuse score is a numerical value that indicates the likelihood of an IP address being involved in malicious activities. The higher the score, the more likely the IP has been used for spam, hacking, or other abusive behaviors. Scores typically range from 0 to 100, with higher scores indicating higher risk.

How often should I check IP reputation?

For general security purposes, it's recommended to check the reputation of suspicious IPs as they interact with your systems. For critical infrastructure, regular monitoring of all incoming IP addresses is advisable. If you're running email servers or public-facing services, weekly or monthly checks of your own IP reputation can help catch issues early.

What should I do if my IP is flagged as malicious?

If your IP address is flagged as malicious, first investigate for any compromised systems, malware, or unauthorized use. Address these issues immediately. Then, contact the abuse email address of your ISP or hosting provider to inform them of the steps you've taken. Finally, submit delisting requests to relevant blacklist operators with evidence of the remediation actions you've taken.
