Perform a reverse DNS lookup to confirm the name is within the `googlebot.com` domain. Subsequently, conduct a forward DNS-to-IP lookup using the `googlebot.com` name. This two-step process ensures the bot's authenticity. Merely doing a reverse DNS isn't enough, as it can be spoofed. Google recommends this method instead of maintaining a public list of IP addresses. Googlebot will also follow robots.txt.\n"]]
