ZNYX Networks, Inc. — 3 prefixes (MA-L)

A MAC address beginning with 00:11:65, 00:C0:95, or E8:8D:F5 belongs to ZNYX Networks, Inc., a Fremont, California vendor of carrier-grade AdvancedTCA (ATCA) and CompactPCI networking and compute hardware. All three prefixes are independent IEEE MA-L (24-bit) blocks registered under the identical company name and street address, so each identifies the same vendor rather than three different companies.

Devices carrying one of these prefixes are typically ATCA blade switches, ATCA processor blades, or CompactPCI Ethernet adapters built for telecom, data-center, energy, and military/aerospace deployments — not consumer or home-network gear.

IEEE assignment

3 prefixes → ZNYX Networks, Inc., registered Fremont, CA, US [Confirmed] — the IEEE MA-L registry (assignments 001165, 00C095, E88DF5)

Registry / block size

MA-L (24-bit OUI); exactly 3 IEEE MA-L blocks held, no MA-M or MA-S (OUI-36) holdings found [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" shown by third-party MAC-lookup tools for these prefixes is a database artifact, not an IEEE fact.

HQ / country

48421 Milmont Drive, Fremont, CA 94538, US [Confirmed] — the IEEE MA-L registry

Company status

Dormant/likely defunct — no company activity found dated after a September 2014 product announcement; znyx.com now 307-redirects to a GoDaddy parked-domain marketplace page [Confirmed] — https://www.znyx.com (redirect observed directly), https://www.prnewswire.com/news-releases/znyx-announces-high-density-b1-top-of-rack-switch-platform-for-security-and-nfv-274312101.html

Exact closure date

Unknown — a search-engine summary sourced to Tracxn claims a 2017 shutdown, but the Tracxn page returned HTTP 429 on direct fetch and no primary source (dissolution filing, dated news article) was found [Unknown] — tracxn.com (unverified)

Device types

ATCA (AdvancedTCA) hub/fabric switches, ATCA blade server platforms and processor blades, CompactPCI Ethernet adapter, 1U NFV/security top-of-rack switch [Confirmed] — prnewswire.com, picmg.org, militaryaerospace.com

Notable products

Verified prefixes (all MA-L, ZNYX Networks, Inc. — the complete set; no other IEEE registrations found under this name)

00:11:65, 00:C0:95, E8:8D:F5 [Confirmed] — the IEEE MA-L registry, the Wireshark manufacturer database

Company founding

Search aggregators (Tracxn) describe a 1992 founding; a LinkedIn search snippet independently names Alan Deikman as "Co-Founder & CTO, ZNYX Networks," but direct verification against a primary record was not possible (Tracxn returned HTTP 429 on fetch)

Security record

No CVE, NVD entry, or vendor security advisory found for ZNYX Networks or any ZX-series product as of an August 2026 search [Confirmed] — nvd.nist.gov, cvedetails.com

Related vendors

Unknown — no parent, subsidiary, or successor company was surfaced in the company-identity research, but no dedicated parent/subsidiary search was run [Unknown] — tracxn.com, linkedin.com/in/alan-deikman

Special note

ZNYX's own September 2014 press release frames its "B1" top-of-rack switch as a platform "for Security and NFV" — that describes the box hosting virtualized firewall/IDS/IPS/antivirus workloads, NOT a disclosed vulnerability in ZNYX's own hardware; do not conflate the two [Confirmed] — https://www.prnewswire.com/news-releases/znyx-announces-high-density-b1-top-of-rack-switch-platform-for-security-and-nfv-274312101.html

Analyst note

A ZNYX Networks OUI identifies carrier-grade ATCA/CompactPCI networking or compute hardware from a Fremont, CA vendor that appears to have gone dormant after 2014; no CVE is recorded as of an August 2026 search, but given the apparent shutdown, a fielded device is best treated as unsupported legacy/EOL hardware on general grounds, not because of a documented vulnerability
