Crawler IP ranges
1,151 address ranges across 9 crawlers, pulled straight from the files their operators publish. Updated 2026-08-31.
These are the lists that settle whether a request claiming to be a crawler actually is. Every one links to its source, so you can check ours against theirs rather than taking our word for it.

A range list is not a bot policy
Matching an address against a list tells you the request came from that operator. It does not tell you what the operator did with the page, whether the same actor is also reaching you from addresses on no list at all, or which of your pages are being taken most.
WebDecoy runs this check on every request that claims a crawler identity, keeps the ones that fail, and links them together when the addresses change.
