About

These IP ranges are sourced from BingBot's official feed and are updated regularly. Use them to verify that requests claiming to be BingBot actually originate from it, or to rate-limit or block it at the network edge. To opt out of crawling entirely, prefer a robots.txt rule — blocking by IP can prevent the crawler from reading your robots.txt at all. Last update was 3 days ago.
