Perplexity-User is the live fetch made when a Perplexity user's question requires reading a specific page. Like ChatGPT-User, it's user-initiated and can cite your page directly.
Perplexity-User publishes the IP ranges it crawls from, from the operator's published feed. A request claiming to be Perplexity-User from an IP outside these ranges is suspect:
A User-Agent string is just a claim — anyone can send Perplexity-User in a header. Confirm identity two ways:
forward-confirmed reverse DNS (the IP resolves to Perplexity, and that host resolves back to the IP), and, where published,
an IP inside the operator's official ranges. If neither holds, it's an impostor wearing the badge — not Perplexity-User.
Recommended: bait. Cites and links to sources and can send you referral traffic — you want this crawler.
If you do choose to act in robots.txt (which crawlers honour but don't enforce):
# Perplexity-User: recommended to ALLOW — blocking can cost you AI visibility User-agent: Perplexity-User Disallow:
Is Perplexity-User really from Perplexity?
Perplexity-User is Perplexity's crawler, but a User-Agent header can be spoofed, so the claim alone isn't proof. Confirm it with forward-confirmed reverse DNS and, where published, a match against Perplexity's official IP ranges.

Should I block Perplexity-User?
Our recommendation: bait. Cites and links to sources and can send you referral traffic — you want this crawler.
