About Bingbot
Bingbot is Microsoft's web crawler for Bing Search, whose index also powers several other search and AI products. Microsoft publishes the ranges Bingbot crawls from, which sit inside Microsoft's wider network.
What traffic from Bingbot addresses usually means
Genuine Bingbot traffic is a search engine indexing your site and should normally be allowed. As with other crawlers, the Bingbot user agent is widely spoofed by scrapers, so verify the address rather than trusting the header.
How to verify a Bingbot IP address
A genuine Bingbot address falls inside Microsoft's published Bingbot ranges and passes forward-confirmed reverse DNS: its PTR record ends in search.msn.com and that hostname resolves back to the same address.

Frequently asked questions
How many IP addresses does Bingbot have?
Bingbot uses 29 IPv4 address blocks. After merging overlapping ranges, the IPv4 blocks cover about 4,752 unique addresses. Counts change as the provider adds, retires or transfers address space.
How can I check if an IP address belongs to Bingbot?
Enter the address in the IPDebrief IP lookup. If it falls inside one of Bingbot's ranges, the profile names the provider alongside the announcing network, location and risk signals. A genuine Bingbot address falls inside Microsoft's published Bingbot ranges and passes forward-confirmed reverse DNS: its PTR record ends in search.msn.com and that hostname resolves back to the same address.
Which ASN does Bingbot use?
Bingbot announces its address space from AS8075. An autonomous system number identifies the network that routes the addresses on the internet; each ASN page lists the analysed addresses observed in that network.
Is traffic from Bingbot IP addresses safe?
Genuine Bingbot traffic is a search engine indexing your site and should normally be allowed. As with other crawlers, the Bingbot user agent is widely spoofed by scrapers, so verify the address rather than trusting the header. Of the 336 Bingbot addresses IPDebrief has analysed, 0 (0%) currently score as higher risk, so judge each address on its own profile.
Where does this IP range data come from?
Ranges are compiled from address lists the operator publishes and from global routing data, refreshed regularly. Address-level risk comes from independent observations of each address, recomputed in the background.
