The OUI prefix 00:80:B0 is assigned to "ADVANCED INFORMATION TECHNOLOGY, INC.", a Japan-based registrant, as an IEEE MA-L (MAC Address Block Large) allocation covering the full 00:80:B0:00:00:00–00:80:B0:FF:FF:FF range (~16.7 million addresses). The assignment is corroborated by multiple independent third-party MAC lookup databases, so the OUI itself is genuine. Beyond the registry facts the public footprint is thin: no active vendor website, no confirmed product lines or device categories, and no security-research context were discoverable in June 2026. Notably, the prefix was absent from the live IEEE OUI text file snapshot fetched in June 2026, which — taken with the lack of public traffic sightings — is consistent with a dormant, historical, or low-volume registrant. The registry address field carries only the country code (JP); no street or city detail is published. Any "registration date" surfaced by third-party tools (e.g. a "2000" value) is a database artifact, not an IEEE-published fact: IEEE publishes no assignment dates in its OUI data. The practical read for asset classification is narrow — a globally-administered 00:80:B0 address ties to this registrant, but with no corroborated device types the OUI gives little beyond the org name and country.
- IEEE assignment
- 00:80:B0 → ADVANCED INFORMATION TECHNOLOGY, INC. [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv line 30076); independently confirmed by macvendorlookup.com, aruljohn.com, macvendors.com, maclookup.app
- Registry / block size
- MA-L (24-bit OUI); single block ~16.7M addresses (00:80:B0:00:00:00–00:80:B0:FF:FF:FF) [Confirmed] — https://maclookup.app/vendors/advanced-information, https://www.macvendorlookup.com/api/v2/00-80-B0. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.
- HQ / country
- JP (Japan) — registry address field carries only the country code; no street/city published in the IEEE MA-L CSV for this assignment [Confirmed] — IEEE MA-L (oui.csv), https://aruljohn.com/mac/0080B0
- Company status
- Unknown — no active vendor website or corporate record was discoverable in public search or lookup databases as of June 2026 [Unknown] — no source
- Device types
- Unknown — no product listings, datasheets, or device-category associations were found in any source [Unknown] — no source
- Notable products
- Unknown — none corroborated
- IEEE current-file status
- not present in the live IEEE OUI text file (standards-oui.ieee.org/oui/oui.txt) as fetched June 2026; may indicate a historical, removed, or low-activity entry, but multiple third-party databases independently confirm the assignment is genuine [Likely] — https://standards-oui.ieee.org/oui/oui.txt
- Registration date
- Unknown — IEEE publishes no assignment dates in its OUI registry. Third-party databases cite a "November 9, 2000" registration and "November 17, 2015" last-updated value; these are database artifacts (crawl/internal timestamps), NOT IEEE facts, and must not be presented as IEEE registration dates [Confirmed as artifact, not as IEEE fact] — https://maclookup.app/vendors/advanced-information
- Security context
- Unknown — no CVEs, vulnerability disclosures, threat-intelligence reports, or spoofing/malicious-infrastructure flags reference this OUI or company in any public source [Unknown] — no source
- Usage context
- Unknown — the MA-L block size (16.7M addresses) is consistent with a manufacturer producing hardware at scale, but no specific product lines, deployment contexts, or network-scan sightings were corroborated [Unknown] — no source
- Source file
- enrichment/registries/oui.csv, line 30076 [Confirmed] — IEEE MA-L
- Analyst note
- A globally-administered 00:80:B0 address resolves to this registrant, but with no confirmed device types the OUI yields little beyond org name + country (JP). Treat the third-party "2000" date as non-authoritative. Absence from the current IEEE text-file snapshot is not refutation — registry CSV and four independent lookup databases agree the assignment exists.
