When your website server logs show a massive amount of crawler requests, how do you quickly identify which ones are legitimate search engine bots like Google or Baidu? This tool instantly verifies whether an input IP belongs to a trusted crawler by comparing it against the official IP databases published by major global search engines. It supports both IPv4 and IPv6 addresses and includes reverse DNS verification in the results, providing crucial data for your website's security.
How can I tell if a detected Baidu spider is real?
Perform a reverse DNS verification: do a forward DNS lookup on the domain name from the PTR record in the results. If the returned IP matches the original address, it is a legitimate crawler.
What if an unrecognized IP shows up as a crawler?
It might be a new spider IP that hasn't been added to the database yet (we recommend manually verifying the DNS records), or a malicious crawler spoofing its User-Agent. You should make a comprehensive judgment based on log characteristics like access frequency.
Search engines update their IP pools monthly, so detection results should be combined with real-time DNS verification. IPv6 addresses must be entered in their fully compressed format (e.g., 2001:db8::1). Queries are limited to one IP at a time; bulk checking is not supported.
Typical verification case: When the check shows "66.249.66.1 → crawl-66-249-66-1.googlebot.com", you should perform an A record lookup for "googlebot.com". If it returns the same IP, it is confirmed as a legitimate Googlebot. Be wary of cases where the User-Agent is "Baiduspider" but the IP is not in the official database; this is usually a scraper tool in disguise.
