Public Network

Floating IP

Overview for end-user:

On the left plane, different floating IP addresses and VPC networks are shown. The right pane is for the creation of new network resources.

When creating new floating IP address:

  • Location - when multiple datacenters locations are provided, the user can choose a location.

  • Billing account* - default billing account is selected if no other is selected from the list.

  • Assign to - By default new IP is unassigned, which means it is not free. End-user VM list is provided for coupling the new floating IP.

  • Name - free text field for identification of the resource.


When an existing resource is selected on the list view, details about that resource are rendered. Users can modify any field with a pencil thumbnail beside it. Floating IP can be assigned to other VM and governing billing account can be changed. Unassign and Delete buttons modify or remove the resource.

Overview for admin:

Cloud provider can set pricing for unassigned floating IPs with support request through provided channels.

Admin can filter and search for connections between users and floating IP addresses in Admin/Ip addresses view.

Public IPv6

If the DC has the IPv6 capability enabled (see below), following features are in place:

  • Newly created VPC networks are assigned a .../112 v6 address sub-net (65534 addresses), which will be shown along with private IPv4 range, e.g.:

  • Newly created VMs are assigned a fixed IPv6 address that is accessible from public Internet.

    This address cannot be moved to other VMs, in contrast to floating IPs.

  • The v6 address provides access to VM over public Internet, and also allows VM to connect to hosts using IPv6.

  • When a VM is created to a VPC network that has no IPv6 range assigned yet, a new range will be allocated for the VPC and the new VM will be assigned an IPv6 address.

Current limitations

  • Existing VMs cannot be assigned an IPv6 address. (This function can be added in future)

  • When a new VM is created with public v6 address, it cannot be opted out or removed. (This can be made more flexible in future)

  • Some OS and App images are not set up to automatically acquire IPv6 address. In that case the OS needs to be configured to run DHCP client for v6 protocol as well.

IPv6 feature support on the service provider side

To use IPv6 features the data center of service provider must be configured with IPv6 stack and one sufficiently big range of public v6 addresses must be assigned to the platform, e.g. a sub-net of /64 size.
