It is possible to add more IP address spaces using the EMnify User Interface (EUI). When you create an account on the EUI, one IP address range is assigned to you, eg: 10.105.193.0/28. This range gives you 14 valid IP addresses which you can assign to your endpoints (devices).
Once you have used the 14 available IP addresses, you need to add a new range of IP. To do so, click on the link symbol on the upper right corner of the EUI:
Here you will see the IP range options.
To add a new IP address range, click on "Allocate IP Address Space" and choose from the drop-down menu the desired IP address Space.
After selecting the new IP address range, click on "Allocate IP address space". You will then be able to use the new available IP addresses.
Using the EUI you can add up to 5 IP address spaces. If you need to add more you can use our API call. More info is available here
