The technical details

Markdown
How to identify it

Look for the Barkrowler identifier in a request’s User-Agent. This is a name match, not identity verification. Version strings may change.

How to check identity

Use Babbar’s published IP ranges and forward-confirmed reverse DNS under babbar.eu.

Access and robots.txt

The operator documents robots.txt rules for this identifier.

Optional full-site opt-out. Merge with existing rules only if intended. robots.txt does not secure private content.

User-agent: Barkrowler
Disallow: /
Seeing 403 or 404 responses?

403 means access was denied; 404 means the resource was not found. Compare the public path, request time, edge security event and origin response to find the cause.

Separate intended restrictions and secret-file probes from pages that should work. A User-Agent name alone does not justify allowing a request.
