rDNS verification (FCrDNS)
Verify a request is genuinely LinkedInBot with forward-confirmed reverse DNS: the client IP's PTR record must end in one of the suffixes below and a forward A/AAAA lookup of that hostname must return the same IP. UA strings alone are spoofable; FCrDNS is not.
.licdn.com.linkedin.com
