MAC address vendor

360 Systems MAC Prefix: Vendor Identified; Device Unknown

Primary prefix
00:05:56
Block
MA-L

Summary

// what this is
360 Systems is registered to MAC prefix 00:05:56 in the IEEE OUI database. When a device's MAC address begins with 00:05:56, that block was registered by 360 Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
RFC 7042 describes EUI-48 identifiers as an assigned initial prefix followed by remaining bits and explains the Group and Local bits. No supplied source maps a 360 Systems product or device category to this exact prefix.

About this vendor.

Updated  ·  Confidence: High  ·  5 sources  ·  How this page is checked

A MAC address beginning 00:05:56 matches an IEEE registry assignment to 360 Systems; the prefix alone does not identify a device category or model. The company describes itself as a manufacturer of professional broadcast video servers and audio record and playout equipment, but the supplied sources do not map those products to this prefix.

The company’s history page says it was founded in 1972, introduced Permanent Playback audio message players in the 1980s, and entered broadcast equipment with the DigiCart recorder in 1990. Its catalog includes TSS video servers, DigiCart 5 and Instant Replay 3 audio systems, and related control software and accessories.

00:05:56 is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values within that block. This is a mathematical address space, not a count of devices or shipments. The first octet is 00, so its Group bit and Local bit are both zero. Those bits are fixed for an exact prefix match; changing either changes the prefix.

Under RFC 7042, an EUI-48 uses an initial assigned prefix and the remaining bits, while the Group and Local bits distinguish address properties. A match establishes registry assignment only, not deployment, product, operating system, or security state.
