Baidu
Baidu documents Baiduspider behavior and robots rules. Baidu does not publish a single downloadable JSON of crawler prefixes like Google or Bing; the prefix list below is a maintained aggregate commonly used for allowlisting, deduplicated to remove subnets wholly covered by a broader entry.
Baiduspider and related crawlers are also frequently observed on China Unicom backbone and IDC space, notably AS4837 and AS23724, in addition to Baidu’s own AS38365/AS55967. Use reverse DNS (*.baidu.com / *.baidu.jp) and vendor guidance - not ASN or static lists alone.
