    """
    Creates an  IPSet , which you use to specify which web requests you want to allow or block based on the IP addresses that the requests originate from. For example, if you're receiving a lot of requests from one or more individual IP addresses or one or more ranges of IP addresses and you want to block the requests, you can create an IPSet that contains those IP addresses and then configure AWS WAF to block the requests.
    To create and configure an IPSet , perform the following steps:
    For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .
