Verify Microsoft IP addresses
Confirm whether a connecting IP from your server logs belongs to Microsoft's published ranges.
1. Find the connecting IP
Look up the connecting client IP ($remote_addr) in your server or proxy logs rather than relying on the User-Agent header.
2. Test against published ranges
Check the address in the tool against published network ranges for Microsoft.
3. Read the result
A match confirms the address is in Microsoft's published ranges. No match means the IP is unlisted or someone is spoofing the name.
Notes on published ranges
- Microsoft recommends refreshing daily; the feed creationTime is not an observation timestamp.
Coverage reflects published network ranges. Some services publish no address lists, and shared ranges can return multiple bots for a single IP.
