Use ModifySubnetAttribute with a CLI - Amazon Elastic Compute Cloud

Use ModifySubnetAttribute with a CLI

The following code examples show how to use ModifySubnetAttribute.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

CLI
AWS CLI

Example 1: To change a subnet's public IPv4 addressing behavior

The following modify-subnet-attribute example modifies subnet-1a2b3c4d to specify that all instances launched into this subnet are assigned a public IPv4 address.

aws ec2 modify-subnet-attribute \
    --subnet-id subnet-1a2b3c4d \
    --map-public-ip-on-launch

This command produces no output.

For more information, see Modify the IP addressing attributes of your subnet in the Amazon VPC User Guide.

Example 2: To change a subnet's IPv6 addressing behavior

The following modify-subnet-attribute example modifies subnet-1a2b3c4d to specify that all instances launched into this subnet are assigned an IPv6 address from the range of the subnet.

aws ec2 modify-subnet-attribute \
    --subnet-id subnet-1a2b3c4d \
    --assign-ipv6-address-on-creation

This command produces no output.

For more information, see IP addressing for your VPCs and subnets in the Amazon VPC User Guide.
