Overview
A subnet is a range of IP addresses within your network. Instances that you launch can be contained within a subnet in your network.
After setting up a network, you can configure multiple subnets. Then you can launch an instance in any subnet that you have created.
Prerequisites
- 'security_manager' user role privilege
Steps
- Go to Manage > Network and click on a network with the Subnet you would like to modify.
- Click on the Subnets tab.
- A list of subnets will display. If there are no subnets, you can Create a Subnet.
- Drop-downs will appear that contain information about the subnet: Info and Audit Entries.
Info
The Info section shows information of the subnet that was defined when the subnet was created.
-
Name: Name of the subnet. You can create up to 20 subnets in a VPC.
-
Resource UID: The unique ID for this resource assigned by the cloud provider.
-
Network: The unique ID for this resource assigned by the cloud provider.
-
Datacenter: This corresponds to Availability Zone in AWS. Resources in Datacenters are logically grouped and are fault isolated from other resources in other Datacenters.
-
CIDR Block: IP Range for the subnet. The subnets CIDR block can be the same as the VPC's CIDR block or a subset of VPC's CIDR block. If you create more than one subnet in a VPC, the subnets CIDR blocks must not overlap. The smallest subnet you can create uses a /28 netmast (16 IP addresses) and the largest uses a /16 netmask (65,536 IP addresses).
-
State: Describes the current state of the subnet. The state of the subnet may be either pending or available.
-
Description: A user-defined description for the subnet. Optional.
Edit Info
- In the upper-right corner, click Edit.
- The table highlights yellow and the Name and Description field can be edited. Currently, these are the only fields that can be changed. Make the changes you need.
- Note: Once the description field been populated with text and saved, you cannot edit the field and leave a blank description.
- Click Save.
Audit Entries
- From the Audit Entries section, you can see information about the actions performed on the subnet. It list the time, summary, and user that perform an action, such as creating, removing, or modifying the subnet.
Note: the audit information in this section is different from the Audit Entries tab of the network. For more information, see Audit Entries.
Note: When you select a specific audit entry, you can see various information about the audit entry, including the Network Href of the subnet. This can be be beneficial if you are using the Networks API. For more information, see the API 1.5 Reference information.
