Hey @Tushar, you can use the describe vpc command for this purpose:

aws ec2 describe-vpcs --vpc-id vpc-1a2b3c4d

You'll see a similar output:

{
    "Vpcs": [
        {
            "VpcId": "vpc-1a2b3c4d", 
            "InstanceTenancy": "default", 
            "Tags": [
                {
                    "Value": "MyVPC", 
                    "Key": "Name"
                }
            ], 
            "CidrBlockAssociations": [
                {
                    "AssociationId": "vpc-cidr-assoc-3781aa5e", 
                    "CidrBlock": "10.0.0.0/16", 
                    "CidrBlockState": {
                        "State": "associated"
                    }
                }, 
                {
                    "AssociationId": "vpc-cidr-assoc-0280ab6b", 
                    "CidrBlock": "10.2.0.0/16", 
                    "CidrBlockState": {
                        "State": "associated"
                    }
                }
            ], 
            "State": "available", 
            "DhcpOptionsId": "dopt-e0fe0e88", 
            "CidrBlock": "10.0.0.0/16", 
            "IsDefault": false
        }
    ]
}
