10Net Communications/DCA (08:00:24)
Summary
- // what this is
- 10Net Communications/DCA is registered to MAC prefix
08:00:24in the IEEE OUI database. When a device's MAC address begins with08:00:24, that block was registered by 10Net Communications/DCA — the OUI identifies the maker of the network hardware, which is not always the brand on the device. 10Net Communications/DCA has ceased operations, but the registration remains on record with IEEE. - // analyst note
- This prefix identifies legacy, long-discontinued PC LAN hardware from a company that no longer operates; treat any device presenting this OUI as pre-1990s-era equipment rather than an active or supported product line.
About this vendor.
A MAC address starting with 08:00:24 belongs to 10Net Communications/DCA, an IEEE-registered OUI tied to legacy Ethernet network interface cards sold for PC local-area networks in the late 1980s and early 1990s.
The registry name traces to a real corporate lineage. The 10Net product line originated at Fox Research and was acquired by Digital Communications Associates Inc. (DCA), based in Alpharetta, GA, in September 1987 for $10M plus up to $6.5M in performance payments — which explains both the "DCA" in the registry name and the Dayton, OH address on this OUI.
In July 1991, Tiara Computer Systems Inc. of Mountain View, CA bought the entire 10Net hardware and software line from DCA for $2.5M, with DCA taking a 10% equity stake in Tiara; Tiara retained the Dayton facility and staff. A second, separate OUI registered at the same Dayton address under the name "TIARA/ 10NET" (08:00:1A) is consistent with that 1991 transition, though it belongs to a distinct registrant and is not part of this vendor's own assignment.
Contemporary trade coverage describes the product line as the "10Net Plus" peer-to-peer network operating system for MS-DOS and Windows, sold together with Ethernet network adaptor cards — the likely hardware class behind this prefix. No device-specific datasheet or teardown tying a model number to 08:00:24 itself was found. No CVE, advisory, or malware association exists for this vendor or OUI as of a September 2026 search, consistent with long-discontinued, pre-internet-era PC LAN hardware with no active product surface.
