When your website server logs show a large number of crawler requests, how can you quickly identify which ones are legitimate spiders from Google, Baidu, and other major search engines? This tool compares against officially published IP address databases from major global search engines and can immediately verify whether an input IP belongs to a trusted crawler. Detection covers IPv4/IPv6 addresses, with results including reverse DNS verification information to provide critical evidence for website security protection.
How do you verify that a detected Baidu spider is authentic?
Perform reverse DNS verification: conduct a forward resolution on the PTR record domain from the detection result; if the returned IP matches the original address, it is a genuine crawler.
What if an IP the tool didn't recognize displays as a crawler?This could mean a new spider IP hasn't been added to the database yet (manual DNS record verification is recommended), or a malicious crawler has forged the User-Agent, requiring comprehensive assessment based on access frequency and other log characteristics.
Search engines update their IP pools monthly; detection results should be combined with real-time DNS verification. IPv6 addresses must be entered in complete compressed format (e.g., 2001:db8::1). Each query is limited to 1 IP; batch detection is not supported.
Typical verification case: When detection shows "66.249.66.1 → crawl-66-249-66-1.googlebot.com", you should perform an A record resolution on "googlebot.com"; if it returns the same IP, confirm it's a legitimate Google crawler. Be wary of cases where the User-Agent is "Baiduspider" but the IP is not in the official database—this is typically spoofed by harvesting tools.
