Niigata Develoment Center, F.I.T. Co., Ltd. — 00:0A:D0 (MA-L)

The IEEE MA-L block 00:0A:D0 (OUI 000AD0) is assigned to "Niigata Develoment Center, F.I.T. Co., Ltd." — and the misspelling "Develoment" is reproduced here deliberately, because it is the exact string recorded in the IEEE registry, not a transcription error on our part. The registered address is Akane-Niigata Building 2F, in Niigata City, Niigata Prefecture, Japan, postal code 950-0944 (a code that maps to the Atago district of Chuo-ku, Niigata-shi). Beyond the registry record, this vendor leaves almost no trace: no current company website, no archived domain, and no English-accessible business-registry entry could be found, so the firm appears small and likely defunct or absorbed. Two data-quality traps are worth flagging for anyone resolving 00:0A:D0. First, an older nmap MAC-prefix file (nmap-6.40) labels this block "MWS," which contradicts both the authoritative IEEE the IEEE MA-L registry and the Wireshark the Wireshark manufacturer database file — treat the nmap label as a data error. Second, the "F.I.T." here is unrelated to Fuserashi International Technology Inc. (the Ohio automotive-fastener company); they are entirely separate entities. The MA-L class means a single 24-bit block (~16.78 million addresses). What kind of device carries this OUI is genuinely unknown — no product listings, device categories, or industry segment surfaced in any accessible source — so a 00:0A:D0 sighting is a low-probability observation with no known security concerns, and an honest "Unknown" on the device side is the correct answer rather than a guess.

IEEE assignment

OUI 000AD0 (00:0A:D0) → Niigata Develoment Center, F.I.T. Co., Ltd. [Confirmed] — IEEE the IEEE MA-L registry (local the IEEE MA-L registry line 641; standards-oui.ieee.org/oui/oui.csv)

Registry / block size

MA-L (24-bit OUI; ~16.78M addresses) [Confirmed] — IEEE the IEEE MA-L registry. No match in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S).

Company name

"Niigata Develoment Center, F.I.T. Co., Ltd." — "Develoment" is the verbatim IEEE registry spelling (a long-standing typo in the original assignment), not our error [Confirmed] — IEEE the IEEE MA-L registry, Wireshark the Wireshark manufacturer database file (line 2751)

Registered address

Akane-Niigata Building 2F, Niigata, Niigata Prefecture, JP 950-0944 (postal code 950-0944 = Atago district, Chuo-ku, Niigata-shi) [Confirmed] — IEEE the IEEE MA-L registry; japanpostalcode.net (950-0944)

Country

JP (Japan) [Confirmed] — IEEE the IEEE MA-L registry

Allocated / registration date

Unknown — IEEE publishes NO assignment/registration date for OUI/MAC-prefix blocks; any "date registered" on a third-party lookup tool is a database artifact, not an IEEE fact [Confirmed that none is published; date itself Unknown] — IEEE the IEEE MA-L registry (columns: Registry, Assignment, Organization Name, Organization Address)

Company status

Unknown — likely defunct or absorbed; no current web presence, active domain, or English-accessible business-registry entry found [Unknown] — no corroborating source located

Vendor website

Unknown / none found — no company site, archived domain, or web presence for this entity (fit-niigata.co.jp and related searches returned no matching company) [Unknown] — no source located

Device types

Unknown — no product listings, device categorization, or industry-segment information found in any accessible source [Unknown] — no source located

Parent / affiliated company

Unknown — none identified. Note: this "F.I.T." is NOT Fuserashi International Technology Inc. (Valley City, Ohio; automotive fasteners), a confirmed separate company [Unknown for this entity; non-match Confirmed] — fitinc.net/global-network

Data trap (nmap)

nmap-6.40's MAC-prefix file lists 000AD0 as "MWS" — a data error in that release; IEEE the IEEE MA-L registry and Wireshark the Wireshark manufacturer database both assign 000AD0 to this vendor. Disregard the nmap label.

[Confirmed] — svn.nmap.org nmap-6.40 nmap-mac-prefixes; IEEE the IEEE MA-L registry

Security context

No CVEs, CISA KEV entries, BIS Entity List entries, or security advisories naming this vendor or OUI 000AD0; no sanctions/regulatory risk identified [Confirmed (no findings)] — cisa.gov/known-exploited-vulnerabilities-catalog

Analyst note

Small, likely-defunct Japanese vendor with no findable web presence; device type unverifiable from any accessible source. A 00:0A:D0 address on a network is a low-probability sighting with no known security concerns. A sourced null is the honest output for the non-registry fields.
