Attached

The number of static and dynamic public IP addresses attached to VMs and VPNs. To learn more about these, see What is the difference between static public IP addresses and dynamic public IP addresses with DNS?

Unattached

The number of static public IP addresses that are not attached to any resource.

Remaining

The number of public IP addresses that can be either:

  • Automatically allocated as dynamic public IPs by the Skytap-managed DNS service
  • Manually allocated as static public IP addresses

If there are no Remaining public IP addresses, you can do one of the following:

2See the account subdomain used by the Skytap-managed DNS service

The account subdomain is part of the pattern used to create fully-qualified domain names (FQDNs) for VMs that have dynamic public IPs with DNS attached. For more information, see What is the account subdomain?

3Filter the list to quickly find public IP addresses

Use the filter options to see public IP addresses by region, type (static or dynamic), and/or by the type of resource they are attached to (VMs in environments, VMs in templates, or VPNs).

4Add static public IP addresses

Adding a static public IP address creates a public IP address that remains reserved for use by VMs in your account until you manually release it. See Adding a static public IP address to your account below.

5Manage individual public IP addresses
  • Use the color indicators to see if a public IP address is deployed (green) or inactive (gray).
  • Click Resources to see the specific resource the VM is attached to.
  • Manage your public IP addresses by detaching or releasing them. See the sections below for more information.

Detaching a static public IP address

You can detach a static public IP address from a VM in an environment or template. Detaching a public IP address removes it from the resource but keeps it in the collection of static public IP addresses available to your account.

To detach a public IP address from an environment or template
  1. Click ip address resources (Resources) next to a public IP address. A list of all resources attached to the public IP address displays.
  2. Click detach (Detach) next to a resource. The public IP address is detached from that resource.
To detach a public IP address from a VPN

Either:

  • Edit the VPN to use a different static public IP address.

    or

  • Delete the VPN.

Releasing a static public IP address

Releasing a static public IP address removes it from your account and makes the public IP address available to other Skytap customers. Do not perform this action until you have removed any manually-created associations with this IP address (for example, registrations with private or public DNS services).

Releasing a static public IP address cannot be undone.


To release a static public IP address that is unattached or attached to an environment or template
  • Click release (Release) next to the static public IP address.


To release a static public IP address that is attached to VPN
  1. Either:

    • Edit the VPN to use a different static public IP address.

      You must also edit the external VPN endpoint to recognize the new static public IP address as the peer IP address.

      or

    • Delete the VPN.

      This action cannot be undone.

  2. Navigate back to the Managing Public IP Addresses page and click release (Release) next to the static public IP address.

Managing dynamic public IP addresses

Adding a dynamic public IP address to your account

Dynamic public IP addresses are automatically managed by the Skytap DNS service. When a VM with a dynamic public IP address and Skytap Cloud-managed DNS name is run, Skytap automatically subtracts a public IP address from your Remaining number of public IP addresses. Skytap randomly uses any available dynamic public IP address; these public IP addresses are shared across all customers.

If there are no Remaining public IP addresses, you can do one of the following:

Detaching or releasing a dynamic public IP address

Dynamic public IP addresses are automatically managed by the Skytap DNS service. When a VM with a dynamic public IP address and Skytap Cloud-managed DNS name is suspended or shut down, Skytap automatically adds a public IP address back to the Remaining number of public IP addresses in your account.
