@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:30:36.140Z") @Stability(Stable) public class CfnIPSet extends CfnResource implements IInspectable
A CloudFormation AWS::WAFv2::IPSet.

This is the latest version of AWS WAF , named AWS WAF V2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Use an IPSet to identify web requests that originate from specific IP addresses or ranges of IP addresses. For example, if you're receiving a lot of requests from a ranges of IP addresses, you can configure AWS WAF to block them using an IP set that lists those IP addresses.

You use an IP set by providing its Amazon Resource Name (ARN) to the rule statement IPSetReferenceStatement , when you add a rule to a rule group or web ACL.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.wafv2.*;
 CfnIPSet cfnIPSet = CfnIPSet.Builder.create(this, "MyCfnIPSet")
         .addresses(List.of("addresses"))
         .ipAddressVersion("ipAddressVersion")
         .scope("scope")
         // the properties below are optional
         .description("description")
         .name("name")
         .tags(List.of(CfnTag.builder()
                 .key("key")
                 .value("value")
                 .build()))
         .build();

      @Stability(Stable) @NotNull public TagManager getTags()
      Key:value pairs associated with an AWS resource.

      The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

      To modify tags on existing resources, use the AWS WAF APIs or command line interface. With AWS CloudFormation , you can only add tags to AWS WAF resources during resource creation.

    • getAddresses

      @Stability(Stable) @NotNull public List<String> getAddresses()
      Contains an array of strings that specifies zero or more IP addresses or blocks of IP addresses.

      All addresses must be specified using Classless Inter-Domain Routing (CIDR) notation. AWS WAF supports all IPv4 and IPv6 CIDR ranges except for /0 .

      Example address strings:

      • To configure AWS WAF to allow, block, or count requests that originated from the IP address 192.0.2.44, specify 192.0.2.44/32 .
      • To configure AWS WAF to allow, block, or count requests that originated from IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24 .
      • To configure AWS WAF to allow, block, or count requests that originated from the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128 .
      • To configure AWS WAF to allow, block, or count requests that originated from IP addresses 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64 .

      For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .
