Ufispace Co., LTD. — 4 prefixes (MA-L)

A MAC address starting with E8:C5:7A, F8:E7:3C, 34:2C:8E, or 5C:07:58 identifies hardware from Ufispace Co., LTD. (styled "UfiSpace Co., Ltd." on its own site), a Taiwan-based networking-equipment manufacturer headquartered in New Taipei City.

IEEE's public registry lists all four blocks as MA-L class, registered to the same organization and address. Holding four separate OUI blocks rather than one corroborates an active, growing vendor rather than a shell registration filed once and abandoned.

UfiSpace builds open, disaggregated networking hardware: telecom fronthaul/core routers (S9500, S9600, S9700 series) and data-center switches spanning 1G-800G (S8901-54XC, S9300-32D, S9301-32DB, S6301 series), sold alongside its NetGence management software. No source found pairs a specific model to one specific OUI block out of the four.

No UfiSpace-specific CVEs or security advisories turned up in search; results surfaced only unrelated Ubiquiti/UniFi vulnerabilities, a different company that is easily confused by name. That is an absence of findings, not a clean bill of health. Separately, the IEEE-registered address (Tucheng District) differs from the address currently listed on ufispace.com (Xinzhuang District) — plausibly an office relocation between the earliest and latest of the four registrations, not a data error.

Registration dates

not published by IEEE for any OUI; third-party "registered" dates (e.g. maclookup.app shows dates ranging 2018-2026 across the 4 blocks) are database artifacts, not IEEE facts [Confirmed] — the IEEE MA-L registry (no date column); https://maclookup.app/vendors/ufispace-co-ltd

Security note

no UfiSpace-specific CVEs/advisories found; search returned only unrelated Ubiquiti/UniFi results [Unknown — absence of findings, not confirmed-secure] — targeted web search, no citable positive source

Related vendors

none found [Unknown]

Analyst note

4 separate OUI blocks plus a real, current product catalog (open networking routers/switches) clears the abstain-on-shells bar — this is not a bare single-OUI registration. No specific model maps to a specific one of the 4 prefixes, so per-prefix device attribution should stay generic ("UfiSpace networking hardware") rather than naming a model.
