CRAY COMMUNICATIONS A/S MAC Addresses
This page provides information about MAC addresses and OUIs assigned to CRAY COMMUNICATIONS A/S. The Organizationally Unique Identifier (OUI) is the first 24 bits of a MAC address and is assigned by the IEEE to uniquely identify a vendor or manufacturer.
About CRAY COMMUNICATIONS A/S MAC Addresses
MAC addresses beginning with 00:00:80: are manufactured by CRAY COMMUNICATIONS A/S. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by CRAY COMMUNICATIONS A/S.
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. CRAY COMMUNICATIONS A/S has been assigned the OUI prefix 000080 (among others) for use in their network devices.

MAC Address Format
A complete MAC address consists of 48 bits (6 bytes) and is typically represented in hexadecimal format with each byte separated by a colon or a hyphen. For CRAY COMMUNICATIONS A/S devices, the MAC address would look like:
00:00:80:XX:XX:XX
The first three bytes (00:00:80) identify the manufacturer as CRAY COMMUNICATIONS A/S, while the last three bytes are unique to each device.
