How to verify DuckAssistBot

Matching the user agent isn't enough, because any client can send it. A real DuckAssistBot request comes from an IP address inside DuckDuckGo's published list:

• https://duckduckgo.com/duckassistbot.json
  486 prefixes · list dated 2026-09-01 · fetched 2026-10-22

The quickest way to check a whole log is our free log checker. It runs in your browser and splits DuckAssistBot requests into real and fake.

Block or allow DuckAssistBot in robots.txt

User-agent: DuckAssistBot
Disallow: /

Use Allow: / instead to explicitly permit it, or build a full file with the AI robots.txt generator. robots.txt is a request, not a lock: it only works for bots that honor it, and only real DuckAssistBot traffic would.
