Private addresses

Here is how the private addresses work.

• Teague: please correct, I left my notebook in SF.

Form:

XXX

First digit: reserved for future use Second digit: cluster # ; 0=UCSF legacy, 1=UofT, 2=UCSF new Third digit: reserved for future use

YYY

First digit: 0=private network ; 1 = IPMI Second digit: rack number Third digit: 0 = physical, 1,2,3,4... = this is a VM

ZZZ

If physical, then second and third digits = physical location in rack.

If virtual, then serial number, starting from 1.

First digit is to handle the case that there are 4 machines in 2U, as in SiM 4-in-1 2U machines.
