It describes itself, inside its own user-agent, as bingbot/2.0
. That is the client's own words, quoted; this page makes no claim about what it is for.
The crawler catalogue on this site has a record for it: /crawler/bingbot.html — what it is for, and what blocking it costs. This page is only what it did here.

Nothing. Every path it asked for existed at the time it asked.
published IP ranges The published ranges we mirror for it are at /ip-ranges/bing-bingbot.html.
From the crawler record at /crawler/bingbot.html, which cites https://www.bing.com/webmasters/help/which-crawlers-does-bing-use-8c184ec0 — one source for both pages.
Not observed. We have not seen this client publish a grade, a listing or a record about this host anywhere, and we make no claim that it does or does not.
It names http://www.bing.com/bingbot.htm in its own user-agent. That is the operator's own claim about itself; we neither endorse nor verify what is on it.

Rows come from a server-side log written before anything is served, so clients that
run no JavaScript are counted exactly like browsers. The window is the whole life of the log,
2026-08-31 20:58:11Z to 2026-09-01 01:55:09Z UTC, and it is stated on every number because a count without a window is
not a fact. Addresses are stored as salted hashes and counted, never printed. Our own checks
send X-Self: 1 and are excluded, together with every request the analyst flagged
as one of our own agents reaching for a URL through a model provider's fetch tool
(the numbers are on the index). Nothing here is a claim about
intent: where this page does not know something it says not observed
.
