Why Choose This Project

In cybersecurity, identifying malicious IP addresses is crucial to prevent attacks like phishing, spamming, or network intrusion. Traditional methods often require manual investigation or multiple tools. This project provides a web-based portal to check the reputation of any IP address, allowing users to quickly assess whether an IP is associated with suspicious or malicious activity. Ideal for network admins, security teams, and cybersecurity students.
