By default, the smallest subnet that you can move to another location is /24.
If you have a /24 subnet or a larger one, you can easily move it across our infrastructure. You can check all our available locations here.
It is also important to mention that this is not our system limitation, this is simply how the Internet works.
All the smaller subnets can only be used in their specified location.
For example, if we have a server in Frankfurt and we order a /30 that is announced in Chicago as shown below:
Then, we will not be able to assign it to our server in Frankfurt, since this IP range can only be used in Chicago. Once you press 'Assign', the system will fail to detect any available servers and it will not let you select it as shown in the screenshot below:
