@Generated(value="jsii-pacmak/1.116.0 (build 0eddcff)", date="2025-10-24T13:34:49.824Z") @Stability(Experimental) public class SubnetV2 extends Resource implements ISubnetV2
(experimental) The SubnetV2 class represents a subnet within a VPC (Virtual Private Cloud) in AWS.

It extends the Resource class and implements the ISubnet interface.

Instances of this class can be used to create and manage subnets within a VpcV2 instance. Subnets can be configured with specific IP address ranges (IPv4 and IPv6), availability zones, and subnet types (e.g., public, private, isolated).

Example: 

 VpcV2 myVpc = new VpcV2(this, "Vpc");
 RouteTable routeTable = RouteTable.Builder.create(this, "RouteTable")
         .vpc(myVpc)
         .build();
 SubnetV2 subnet = SubnetV2.Builder.create(this, "Subnet")
         .vpc(myVpc)
         .availabilityZone("eu-west-2a")
         .ipv4CidrBlock(new IpCidr("10.0.0.0/24"))
         .subnetType(SubnetType.PRIVATE_ISOLATED)
         .build();
 NatGateway natgw = NatGateway.Builder.create(this, "NatGW")
         .subnet(subnet)
         .vpc(myVpc)
         .connectivityType(NatConnectivityType.PRIVATE)
         .privateIpAddress("10.0.0.42")
         .build();
 Route.Builder.create(this, "NatGwRoute")
         .routeTable(routeTable)
         .destination("0.0.0.0/0")
         .target(Map.of("gateway", natgw))
         .build();
