Cadence Design Systems, Inc. — 2 prefixes (MA-L)
Summary
- // what this is
- Cadence Design Systems is registered to MAC prefix
0030C5and 1 more in the IEEE OUI database. When a device's MAC address begins with0030C5, that block was registered by Cadence Design Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both 0030C5 and AC6B0F are Cadence Design Systems' own exclusive IEEE MA-L /24 blocks, not shared IEEE-RA bases, so devices carrying either prefix can be attributed to Cadence. They most plausibly appear on Cadence's networked verification hardware, such as its Palladium or Protium systems, though no source confirms a specific device-to-prefix mapping.
About this vendor.
A MAC address beginning 00:30:C5 or AC:6B:0F belongs to Cadence Design Systems, Inc., a large publicly traded electronic design automation (EDA) company, and most plausibly appears on Cadence's own networked verification hardware rather than on a shared IEEE-RA block.
Cadence holds two separate IEEE MA-L assignments in the registry, both registered to San Jose, CA addresses: 0030C5 (555 River Oaks Parkway) and AC6B0F (2670 Seely Ave). Holding multiple independent OUI blocks under the same corporate name is itself a substance signal — the opposite of a bare single-OUI shell registration.
Cadence is a substantial, identifiable company: founded 1983 in San Jose, trading as NASDAQ: CDNS, an S&P 500 component, with reported 2025 revenue near $5.3 billion and roughly 13,800 employees. Its core business is EDA software for chip, IC, SoC, and PCB design, not network-hardware manufacturing in the traditional sense.
Cadence also sells enterprise hardware — the Palladium emulation platforms and the Protium FPGA-based prototyping platforms — used by chip-design customers and plausibly requiring networked management interfaces. No source ties either OUI block explicitly to a named product line, so this device-type link is an inference from Cadence's known hardware catalog, not a confirmed mapping.
No CVE or documented security incident tied to Cadence Design Systems' networked hardware was found as of a September 2026 search. Two unrelated same-name hits surfaced during research — an open-source workflow project and a JetBrains product, both also called "Cadence" — neither concerns this company or its hardware.
