nRF9160 DeviceID unicity

[Saketaram]

Hi,

Could you confirm that DeviceID found in FICR of nRF9160 is:

1/ randomly generated (64 bits = 8 bytes)

2/ they are not unique, but already on the chip when it is shipped out of Nordic warehouses

3/ they don't change over time, unless we change them 

Thanks in advance

Here are the answers I got;

1/ Yes

2/ Yes. Code is random but I guess some probability exists that duplicates are created.

3/ Yes
