NIC is the abbreviation for ''Number In a Can''.  Dallas Semiconductor which today is part of Maxim Integrated Products chose this perhaps not very fortunate name to describe the iButton 1-wire devices used for hardware identification on [[SGI Origin]], [[SGI Octane]] and later systems. Most later "NICs" are not really metal cans, but small 6-pin SMD chips, usually DS2505 ones (the exceptions are MAC NICs on IP27 systems and [[IOC3]] [http://en.wikipedia.org/wiki/PCI PCI] and [[IOC3|MENET]] [[XIO]] cards, which use DS1981U NICs and IP30 systems which use a DS2502).

A NIC contains a 64-bit unique address that is used to identify it inside a system and possible some OTP (One-Time Programmable) EPROM. The unique address is not used for anything by SGI software. However, the OTP memory contains important information on the device containing the particular NIC:
