FlexIPs

FlexIPs are public IPs that can point to any slice in the same region. You can use them to build redundancy, or instantly switch services between slices without changing DNS. FlexIPs stay in your account until deleted. IPv4 addresses are charged hourly at a maximum $5.00/month each, due to exhaustion of IPv4 space. FlexIPv6 addresses are free.

Note

In accordance with ARIN policy, there is a default limit of 2 FlexIPv4 addresses per primary account. You can request an increase in the account settings page by clicking Request Increase at the top of the page.

Assign

Assigning a FlexIP is very easy:

  1. Select the slice you would like initially assign to your new IP.

  2. Click Assign Flex IP

The system should assign your new IP and it will show up in the table below. Once complete, you should be able to connect to the assigned slice at the new IP. All ports and services are mirrored to this IP.

Note

All firewalls for a slice (if any), are also applied to any FlexIPs assigned to it.

For each assigned FlexIP there is an ellipsis dropdown menu with the following options:

Reassign

Reassign this FlexIP to a different slice. You will be prompted for the slice you would like to reassign it to. Select the slice and click Reassign. The panel will indicate when reassignment is complete, and you should be able to connect.

Note

If you reassign a FlexIP to a new slice, SSH will give the notorious “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!” upon trying to reconnect for the first time. This is correct and to be expected, because the host key has indeed changed due to the IP change.

Unassign

Unassign a FlexIP from a slice. This does not delete the FlexIP from your account. You can keep it and reassign it to any other slice whenever you want.

Delete

Delete a FlexIP from your account. You will be prompted to confirm. Once confirmed, the FlexIP will be unassigned from any slice it is currently assigned to (if any), removed from your account and the billing will stop.

Note

In order for a Regular subuser to unassign a FlexIP, they must also have readwrite permissions to the slice they are unassigning it from.
