rDNS verification (FCrDNS)
Verify a request is genuinely Googlebot-Image 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.
.1e100.net.googlebot.com.googleusercontent.com
