/**
 * <p>Associates Elastic IP addresses (EIPs) and private IPv4 addresses with a public NAT gateway. For more information,
 *             see <a href="https://docs.aws.amazon.com/vpc/latest/userguide/nat-gateway-working-with.html">Work with NAT gateways</a> in the <i>Amazon VPC User Guide</i>.</p>
 *          <p>By default, you can associate up to 2 Elastic IP addresses per public NAT gateway. You can increase the limit by requesting a quota adjustment.
 *             For more information, see <a href="https://docs.aws.amazon.com/vpc/latest/userguide/amazon-vpc-limits.html#vpc-limits-eips">Elastic IP address quotas</a> in the <i>Amazon VPC User Guide</i>.</p>
 *          <important>
 *             <p>When you associate an EIP or secondary EIPs with a public NAT gateway, the network border group of the EIPs
 *             must match the network border group of the Availability Zone (AZ) that the public NAT gateway is in. If it's not the same,
 *             the EIP will fail to associate. You can see the network border group for the subnet's AZ by viewing the details of the subnet.
 *             Similarly, you can view the network border group of an EIP by viewing the details of the EIP address. For more information
 *             about network border groups and EIPs, see <a href="https://docs.aws.amazon.com/vpc/latest/userguide/WorkWithEIPs.html">Allocate an Elastic IP address</a> in the <i>Amazon VPC User Guide</i>.
 *         </p>

 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, AssociateNatGatewayAddressCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, AssociateNatGatewayAddressCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // AssociateNatGatewayAddressRequest
 *   NatGatewayId: "STRING_VALUE", // required
 *   AllocationIds: [ // AllocationIdList // required
 *     "STRING_VALUE",
 *   ],
 *   PrivateIpAddresses: [ // IpList
 *     "STRING_VALUE",
 *   ],
 *   DryRun: true || false,
 * };
 * const command = new AssociateNatGatewayAddressCommand(input);
 * const response = await client.send(command);
 * // { // AssociateNatGatewayAddressResult
 * //   NatGatewayId: "STRING_VALUE",
 * //   NatGatewayAddresses: [ // NatGatewayAddressList
 * //     { // NatGatewayAddress
 * //       AllocationId: "STRING_VALUE",
 * //       NetworkInterfaceId: "STRING_VALUE",
 * //       PrivateIp: "STRING_VALUE",
 * //       PublicIp: "STRING_VALUE",
