Search engine crawlers, monitoring tools, and legitimate automation that provide value to websites.
Malicious bots that scrape content, spam forms, or attempt to exploit vulnerabilities.
IP addresses can reveal important clues about whether a visitor is likely a bot or human.
Many bots operate from datacenter IP ranges rather than residential IPs. These IPs are often assigned to cloud providers.
// Check if IP is from a known datacenter
const datacenterRanges = ['192.168.0.0/16', '10.0.0.0/8'];
const isDatacenter = checkIPRange(ip, datacenterRanges);
Requests from unusual locations or rapid location changes can indicate bot behavior.
// Check for suspicious geographic patterns
if (user.location !== expectedLocation) {
flagAsSuspicious('location_mismatch');
}
Some IPs have known reputations for spam or malicious activity.
// Check IP against reputation databases
const reputation = await checkIPReputation(ip);
if (reputation.score > 0.7) {
blockRequest('bad_reputation');
}
User agent strings provide detailed information about the client making the request.
Analyzing user behavior can help distinguish bots from humans.
Use IP2FY's geolocation data to enhance your bot detection capabilities.
async function detectBot(ip, userAgent) {
// Get IP geolocation data
const response = await fetch(`https://api.ip2fy.com/${ip}`);
const geoData = await response.json();
let botScore = 0;
// Check if IP is from datacenter
if (geoData.org && geoData.org.includes('Amazon') ||
geoData.org && geoData.org.includes('Microsoft')) {
botScore += 0.3;
}
// Check user agent for bot signatures
const botSignatures = ['python-requests', 'curl', 'bot', 'spider'];
if (botSignatures.some(sig => userAgent.toLowerCase().includes(sig))) {
botScore += 0.5;
}
// Check for unusual locations
if (geoData.country === 'Unknown' || !geoData.city) {
botScore += 0.2;
}
return {
isBot: botScore > 0.5,
score: botScore,
geoData: geoData
};
}
Use multiple signals (IP, user agent, behavior) rather than relying on a single method.
Allow legitimate bots like Googlebot and Bingbot to ensure proper indexing.
Implement rate limiting to prevent abuse regardless of bot detection accuracy.
Keep your detection rules updated as bot behaviors evolve over time.
Ensure your bot detection practices comply with applicable privacy regulations.
Regularly test your detection to avoid blocking legitimate users.
