**Example 1: To describe your subnets** The following ``describe-subnets`` example displays the details of your subnets. :: aws ec2 describe-subnets Output:: { "Subnets": [ { "AvailabilityZone": "us-east-1d", "AvailabilityZoneId": "use1-az2", "AvailableIpAddressCount": 4089, "CidrBlock": "172.31.80.0/20", "DefaultForAz": true, "MapPublicIpOnLaunch": false, "MapCustomerOwnedIpOnLaunch": true, "State": "available", "SubnetId": "subnet-0bb1c79de3EXAMPLE", "VpcId": "vpc-0ee975135dEXAMPLE", "OwnerId": "111122223333", "AssignIpv6AddressOnCreation": false, "Ipv6CidrBlockAssociationSet": [], "CustomerOwnedIpv4Pool:": 'pool-2EXAMPLE', "SubnetArn": "arn:aws:ec2:us-east-2:111122223333:subnet/subnet-0bb1c79de3EXAMPLE" }, { "AvailabilityZone": "us-east-1d", "AvailabilityZoneId": "use1-az2", "AvailableIpAddressCount": 4089, "CidrBlock": "172.31.80.0/20", "DefaultForAz": true, "MapPublicIpOnLaunch": true, "MapCustomerOwnedIpOnLaunch": false, "State": "available", "SubnetId": "subnet-8EXAMPLE", "VpcId": "vpc-3EXAMPLE", "OwnerId": "1111222233333", "AssignIpv6AddressOnCreation": false, "Ipv6CidrBlockAssociationSet": [], "Tags": [ { "Key": "Name", "Value": "MySubnet" } ], "SubnetArn": "arn:aws:ec2:us-east-1:111122223333:subnet/subnet-8EXAMPLE" } ] } For more information, see `Working with VPCs and Subnets `__ in the *AWS VPC User Guide*. **Example 2: To describe a specificied VPCs subnets** The following ``describe-subnets`` example uses a filter to retrieve details for the subnets of the specified VPC. :: aws ec2 describe-subnets \ --filters "Name=vpc-id,Values=vpc-3EXAMPLE" Output:: { "Subnets": [ { "AvailabilityZone": "us-east-1d", "AvailabilityZoneId": "use1-az2", "AvailableIpAddressCount": 4089, "CidrBlock": "172.31.80.0/20", "DefaultForAz": true, "MapPublicIpOnLaunch": true, "MapCustomerOwnedIpOnLaunch": false, "State": "available", "SubnetId": "subnet-8EXAMPLE", "VpcId": "vpc-3EXAMPLE", "OwnerId": "1111222233333", "AssignIpv6AddressOnCreation": false, "Ipv6CidrBlockAssociationSet": [], "Tags": [ { "Key": "Name", "Value": "MySubnet" } ], "SubnetArn": "arn:aws:ec2:us-east-1:111122223333:subnet/subnet-8EXAMPLE" } ] } For more information, see `Working with VPCs and Subnets `__ in the *AWS VPC User Guide*. **Example 3: To describe subnets with a specific tag** The following ``describe-subnets`` example uses a filter to retrieve the details of those subnets with the tag ``Name=MySubnet``. The command specifies that the output is a simple text string. :: aws ec2 describe-subnets \ --filters Name=tag:Name,Values=MySubnet \ --output text Output:: SUBNETS False us-east-1c use1-az1 250 10.0.0.0/24 False False False 111122223333 available arn:aws:ec2:us-east-1:111122223333:subnet/subnet-0d3d002af8EXAMPLE subnet-0d3d002af8EXAMPLE vpc-0065acced4EXAMPLE TAGS Name MySubnet For more information, see `Working with VPCs and Subnets `__ in the *AWS VPC User Guide*.
