We are announcing today a limit increase to the number of CIDR or IP Address entries customers can have within an IPSet condition in an AWS WAF Rule. We have increased the limit from 1,000 to 10,000 entries per condition. Customers who want even larger lists of IP addresses can create multiple rules. With this limit increase customers can now import larger IP reputational lists and customer who have multiple IPSet rules can now consolidate them into fewer rules. As you know, IPSet Rules are used to specify which web requests customers want to allow or block based on the IP addresses that the requests originate from.
