CensysInspect: what it is, its IP ranges, and how to block it

CensysInspect is Censys's internet scanner.

Verified by	Published addresses
Its vendor's address list	`https://docs.censys.com/docs/opt-out-of-data-collection.md`

It probes every address on the internet for its exposed services, and sends nobody back. Bot Protection blocks it by default; you can let it through.

How to verify it

Any bot can write CensysInspect in its User-Agent. A request is CensysInspect only when its address is in Censys's published list below: check the address, not the name.

How to block it

Bot Protection verifies CensysInspect by its address on every request and answers it as you choose on the Set-up page, per kind or for CensysInspect alone; a bot that only wears the name is judged like any other bot.
