Agilent Technologies, Inc. — 2 confirmed MA-L prefixes

A MAC address beginning with 00:30:D3 or 00:04:43 belongs to Agilent Technologies, Inc., and typically identifies networked laboratory instruments — chromatography data systems and microarray scanners — rather than office or consumer equipment.

Agilent was spun off from Hewlett-Packard on November 1, 1999, in what was then the largest Silicon Valley IPO at $2.1B. The company trades as NYSE: A, employs roughly 18,100 people, and reported about $6.95B in FY2025 revenue, headquartered at 5301 Stevens Creek Boulevard, Santa Clara, CA.

Agilent later spun off Lumileds (2005), Avago Technologies (2005, now part of Broadcom), Verigy (2006), and Keysight Technologies (2014, its electronic-measurement division and now a DONE entry in this repo), while acquiring Varian, Inc. in 2010. That acquisition brought a Torino, Italy manufacturing site now registered as the related but separately-named "Agilent S.p.A."

Two MA-L blocks are directly registered to "Agilent Technologies, Inc.": 00:30:D3, at 1501 Page Mill Road, Palo Alto, and 00:04:43, at Agilent's current Santa Clara headquarters. IEEE's registry publishes no assignment date for either block; maclookup.app's per-prefix dates (2000-11-09 and 2000-12-04) are that tool's own database artifact, not an IEEE fact.

Two other registry rows mention Agilent without Agilent owning them: 00:0C:64 (X2 MSA Group) and 00:08:BE (XENPAK MSA Group) list an Agilent office in Ipswich, UK, only as a mailing address for these fiber-optic-transceiver industry consortia — a common trap when grepping a registry for the word "Agilent."

Confirmed CVEs exist for Agilent's instrument-control software — remote code execution in 2100 Expert (CVE-2014-5145) and in the Feature Extraction ActiveX control (CVE-2015-2092) — but neither is tied to the Ethernet NIC hardware carrying these OUIs; as of an August 2026 search, no hardware- or firmware-specific advisory was found for either prefix.

IEEE assignment

2 prefixes → Agilent Technologies, Inc., registered Palo Alto, CA and Santa Clara, CA, US [Confirmed] — the IEEE MA-L registry 0030D3, 000443

Registry / block size

MA-L (24-bit OUI); exactly 2 confirmed IEEE prefixes under the exact name "Agilent Technologies, Inc." [Confirmed] — the IEEE MA-L registry; cross-checked against maclookup.app, which lists the same 2 prefixes and no others

HQ / country

5301 Stevens Creek Boulevard, Santa Clara, CA 95051, US (current HQ; matches the 00:04:43 registered address) [Confirmed] — agilent.com

Company status

active; NYSE: A, S&P 500 constituent; FY2025 revenue ~$6.95B, ~18,100 employees [Confirmed] — agilent.com, investor.agilent.com

Device types

chromatography (LC/GC) data systems and microarray scanners, commonly networked via the G1369A LAN Interface card and controlled through ChemStation/OpenLAB CDS software [Likely] — agilent.com (the specific OUI-to-card model pairing is not independently confirmed)

Notable products

2100 Bioanalyzer, SureScan microarray scanner, ChemStation/OpenLAB CDS software

Verified sample prefixes (both MA-L, Agilent Technologies, Inc.)

00:30:D3, 00:04:43 [Confirmed] — the IEEE MA-L registry; maclookup.app

Registration dates

none published by IEEE — the public OUI registry has no assignment-date field; maclookup.app's per-prefix dates (00:30:D3: 2000-11-09; 00:04:43: 2000-12-04) are a third-party database artifact, not an IEEE fact [Confirmed] — maclookup.app

Special note (data trap)

00:0C:64 (X2 MSA Group) and 00:08:BE (XENPAK MSA Group) list an Agilent Ipswich, UK address as a care-of contact but are NOT Agilent-owned — both are fiber-optic-transceiver industry consortia that used the address only for mail [Confirmed] — the IEEE MA-L registry 000C64, 0008BE

Related vendors

Agilent S.p.A. (Torino, IT — the former Varian, Inc. site, acquired by Agilent in 2010) holds a separate MA-M block, not counted in this entry [Confirmed] — the IEEE MA-M registry 8C147D2; Keysight Technologies (2014 spin-off of Agilent's electronic-measurement division; already a DONE entry in this repo)

[Confirmed] — /mac/vendor/keysight-technologies/

Analyst note

Agilent's confirmed CVEs (2100 Expert RCE, Feature Extraction ActiveX RCE) are software-layer and not tied to the Ethernet NIC hardware carrying these OUIs; as of an August 2026 search, no hardware- or firmware-specific advisory exists for either prefix
