Get the subnet and VPC id of a running EC2 instance

Raw

ec2-instance-subnet-id.md

First get the Interface mac address, then use that to run the full command

INTERFACE=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/)
SUBNET_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/subnet-id)
VPC_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/vpc-id)

echo $SUBNET_ID

Not sure this will work if you have more than one network interface
