Verwenden Sie es CreateSubnet mit einem oder AWS SDK CLI

Beispiel 1: Um ein Subnetz nur mit einem IPv4 CIDR Block zu erstellen

Das folgende create-subnet Beispiel erstellt ein Subnetz im angegebenen Bereich VPC mit dem angegebenen IPv4 CIDR Block.

aws ec2 create-subnet \
    --vpc-id vpc-081ec835f3EXAMPLE \
    --cidr-block 10.0.0.0/24 \
    --tag-specifications ResourceType=subnet,Tags=[{Key=Name,Value=my-ipv4-only-subnet}]

Ausgabe:

{
    "Subnet": {
        "AvailabilityZone": "us-west-2a",
        "AvailabilityZoneId": "usw2-az2",
        "AvailableIpAddressCount": 251,
        "CidrBlock": "10.0.0.0/24",
        "DefaultForAz": false,
        "MapPublicIpOnLaunch": false,
        "State": "available",
        "SubnetId": "subnet-0e99b93155EXAMPLE",
        "VpcId": "vpc-081ec835f3EXAMPLE",

        "Ipv6CidrBlockAssociationSet": [],
        "Tags": [
            {
                "Key": "Name",
                "Value": "my-ipv4-only-subnet"
            }
        ],
        "SubnetArn": "arn:aws:ec2:us-west-2:123456789012:subnet/subnet-0e99b93155EXAMPLE"
    }
}

Beispiel 2: Um ein Subnetz mit Blöcken sowohl als auch IPv4 zu erstellen IPv6 CIDR

Im folgenden create-subnet Beispiel wird ein Subnetz im angegebenen Bereich VPC mit den angegebenen Blöcken IPv4 und IPv6 CIDR erstellt.

aws ec2 create-subnet \
    --vpc-id vpc-081ec835f3EXAMPLE \
    --cidr-block 10.0.0.0/24 \
    --ipv6-cidr-block 2600:1f16:cfe:3660::/64 \
    --tag-specifications ResourceType=subnet,Tags=[{Key=Name,Value=my-ipv4-ipv6-subnet}]

Ausgabe:

{
    "Subnet": {
        "AvailabilityZone": "us-west-2a",
        "AvailabilityZoneId": "usw2-az2",
        "AvailableIpAddressCount": 251,

            {
                "AssociationId": "subnet-cidr-assoc-06c5f904499fcc623",
                "Ipv6CidrBlock": "2600:1f13:cfe:3660::/64",
                "Ipv6CidrBlockState": {
                    "State": "associating"
                }
            }
        ],
        "Tags": [
            {
                "Key": "Name",
                "Value": "my-ipv4-ipv6-subnet"
            }
        ],
        "SubnetArn": "arn:aws:ec2:us-west-2:123456789012:subnet/subnet-0736441d38EXAMPLE"
    }
}

Beispiel 3: Um ein Subnetz nur mit einem IPv6 CIDR Block zu erstellen

Das folgende create-subnet Beispiel erstellt ein Subnetz im angegebenen Bereich VPC mit dem angegebenen IPv6 CIDR Block.

aws ec2 create-subnet \
    --vpc-id vpc-081ec835f3EXAMPLE \
    --ipv6-native \
    --ipv6-cidr-block 2600:1f16:115:200::/64 \
    --tag-specifications ResourceType=subnet,Tags=[{Key=Name,Value=my-ipv6-only-subnet}]
