Current and historic Googlebot IP addresses
Every IP address in the Googlebot API carries a status. A current IP address was confirmed within the past 12 months, through observed crawl activity or through the IP address lists published by the bot operator. A historic IP address has older confirmations only.
Historic records stay in the database on purpose. Log file analysis often covers older date ranges, and a lookup on aged logs still needs a match for the IP addresses in use back then.
