Microsoft list of Bingbot IP addresses released

Bingbot is a web crawling robot created by Microsoft. It is used to index webpages for the Bing search engine. The Microsoft list of Bingbot IP addresses is a list of IP addresses that are used by Bingbot to crawl websites. This list is released by Microsoft to allow webmasters to control access to their websites.

The list of Bingbot IP addresses is updated periodically and contains both IPv4 and IPv6 addresses. The list can be found on the Microsoft website and can be used to configure access control rules on web servers. This allows webmasters to whitelist or blacklist IP addresses to control which requests are allowed or blocked. This can help protect websites from malicious actors, as well as limit access by legitimate crawlers such as Bingbot.

The list of Bingbot IP addresses is organized by geographic region. This allows webmasters to control access to their websites based on location. For example, if a website owner wants to block requests from certain countries, they can use the list to create access control rules that limit requests from the specified countries.
