F5 ASM Support ID

Hi,

Can anyone tell me the format of Support ID which being genereated by F5 ASM for blocking request. Does it differs from per device.

One of my ASM support ID starts with 18375xxxxxx and other one support ID starts with 43520xxxx.

So the support ID generated from one F5 ASM device would be same ( i mean the first 5-6 digits) for all blocking request ?

By seeing the support ID can we assume if it is from my devices or does it from some other F5 devices ?

Appreciate your help.
