MAC address vendor

Addonics Technologies, Inc. — 00:50:C8 (MA-L)

Primary prefix
00:50:C8
Block
MA-L
Status
Active

Summary

// what this is
Addonics Technologies is registered to MAC prefix 00:50:C8 in the IEEE OUI database. When a device's MAC address begins with 00:50:C8, that block was registered by Addonics Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
00:50:C8 identifies Addonics Technologies as the registrant on a globally-administered address; this is the company's only known OUI block, so absence of this prefix says nothing about the vendor either way.

About this vendor.

Updated  ·  Confidence: Medium  ·  11 sources  ·  How this page is checked

A MAC address starting with 00:50:C8 belongs to Addonics Technologies, Inc., typically seen on the company's storage-and-connectivity hardware — network-attached-storage bridges, RAID towers, and HDD/SSD duplicators that carry an onboard Ethernet interface.

The registration itself is a single MA-L (large, /24) block, registered to "Addonics Technologies, Inc." at 1918 Junction Ave., San Jose, CA 95131, US. No matching rows appear under the same name in the MA-M (the IEEE MA-S registry) or MA-S (the IEEE MA-M registry) registries, so this is a one-block vendor, not a multi-OUI holder.

Addonics is a real, long-operating manufacturer rather than a bare shell registration: it runs a public corporate site, has been reviewed by TechCrunch, Ubergizmo, and phys.org, and lists Ethernet-bearing products — NAS/USB bridge adapters, a Gigabit Ethernet PCI-E controller, and a WiFi Drive Adapter with an RJ45 port — consistent with holding a MAC OUI. No independent source was found tying the specific 00:50:C8 prefix to one named product, so that link is plausible but not separately confirmed.

Company-history sources disagree: third-party aggregators (LeadIQ, Crunchbase) describe incorporation in 1998 in Silicon Valley, California, matching the San Jose registry address, while Addonics' own site states the company was founded in 1997 in Taipei, Taiwan, where its present HQ and manufacturing sites sit. Both could describe the same company at different stages, but the discrepancy was not independently reconciled. No CVE or malware association was found as of an August 2026 search.
