10 These methods manage subnet objects and the routing among them. A VPC
11 may have a single subnet or many, and routing rules determine whether
12 the subnet has access to the internet ("public"), is entirely private,
13 or is connected to a customer gateway device to form a Virtual Private
14 Network (VPN) in which your home network's address space is extended
15 into the Amazon VPC.
16
17 All instances in a VPC are located in one subnet or another. Subnets
18 may be public or private, and are organized in a star topology with a
19 logical router in the middle.
20
21 Although all these methods can be called from VM::EC2 objects, many are
22 more conveniently called from the VM::EC2::VPC object family. This
23 allows for steps that typically follow each other, such as creating a
24 route table and associating it with a subnet, happen automatically. For
25 example, this series of calls creates a VPC with a single subnet,
26 creates an Internet gateway attached to the VPC, associates a new route
27 table with the subnet and then creates a default route from the subnet
28 to the Internet gateway.

44 $subnet = $ec2->create_subnet(-vpc_id=>$id,-cidr_block=>$block)
45 This method creates a new subnet within the given VPC. Pass a VPC
46 object or VPC ID, and a CIDR block string. If successful, the method
47 will return a VM::EC2::VPC::Subnet object.
48
49 Required arguments:
50
51 -vpc_id A VPC ID or previously-created VM::EC2::VPC object.
52
53 -cidr_block A CIDR block string in the form "xx.xx.xx.xx/xx". The
54 CIDR address must be within the CIDR block previously
55 assigned to the VPC, and must not overlap other subnets
56 in the VPC.
57
58 Optional arguments:
59
60 -availability_zone The availability zone for the instances launched
61 within this instance, either an availability zone
62 name, or a VM::EC2::AvailabilityZone object. If
63 this is not specified, then AWS chooses a zone for
64 you automatically.
65
66 $success = $ec2->delete_subnet($subnet_id)
67 $success = $ec2->delete_subnet(-subnet_id=>$id)
68 This method deletes the indicated subnet. It may be called with a
69 single argument consisting of the subnet ID, or a named argument form
70 with the argument -subnet_id.
71
72 @subnets = $ec2->describe_subnets(@subnet_ids)
73 @subnets = $ec2->describe_subnets(\%filters)
74 @subnets = $ec2->describe_subnets(-subnet_id=>$id, -filter => \%filters)
75 This method returns a list of VM::EC2::VPC::Subnet objects. Called with
76 no arguments, it returns all Subnets (not filtered by VPC Id). Pass a
77 list of subnet IDs or a filter hashref in order to restrict the search.
78
79 Optional arguments:
80
81 -subnet_id Scalar or arrayref of subnet IDs.
82 -filter Hashref of filters.
83
84 Available filters are described at
85 http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSubnets.html
86
87 $success = $ec2->modify_subnet_attribute(-subnet_id => $sub_id,
88 -map_public_ip_on_launch => $boolean)
89 Modifies a subnet attribute.
90
91 Required arguments:
92
93 -subnet_id The ID of the subnet to modify.
94
95 -map_public_ip_on_launch Modifies the public IP addressing behavior for the
96 subnet. Specify true to indicate that instances
97 launched into the specified subnet should be
98 assigned a public IP address. If set to true, the
99 instance receives a public IP address only if the
100 instance is launched with a single, new network
101 interface with the device index of 0.
102
103 Returns true on success.
