• createObject
  For IPSec network tunnels, customers can create their local subnets using this method. After the customer is created successfully, the customer subnet can then be added to the IPSec network tunnel.
• getIpAddresses
  All ip addresses associated with a subnet.
• getObject
  getObject retrieves the SoftLayer_Network_Customer_Subnet object whose ID number corresponds to the ID number of the init parameter passed to the SoftLayer_Network_Customer_Subnet service. You can only retrieve the subnet whose account matches the account that your portal user is assigned to.
• SoftLayer_Network_Customer_Subnet
  The SoftLayer_Network_Customer_Subnet data type contains general information relating to a single customer subnet (remote).
• SoftLayer_Network_Customer_Subnet
  Every Customer subnet is defined in the SoftLayer_Network_Customer_Subnet service. SoftLayer keeps track of subnets outside of the SoftLayer Network that are associated to SoftLayer subnets or systems. For example, customer subnets are tracked for proper management of network tunnels. This service allows for managing subnets on the remote end of the network tunnel.
