To change a subnet's public IPv4 addressing behavior

This example modifies subnet-1a2b3c4d to specify that all instances launched into this subnet are assigned a public IPv4 address. If the command succeeds, no output is returned.

Command:

To change a subnet's IPv6 addressing behavior

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

Command:

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