rDNS verification (FCrDNS)
Verify a request is genuinely YandexMobileBot 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.
.yandex.com.yandex.net.yandex.ru
