rDNS verification (FCrDNS)
Verify a request is genuinely dotbot 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.
.dotbot.com.moz.com.rogerbot.com
