Verify a request is really Bytespider

No published IP list or verification method exists.

ByteDance publishes no documentation page for Bytespider at all (searched 2026-08-04). Every other crawler in this index has an operator page to cite; this one's entry is defined by that absence. The user-agent string seen in access logs carries a spider-feedback@bytedance.com contact address, which is the only operator-published artifact, and it is inside the request itself.
