Shuttle Inc. — 3 prefixes (MA-L)

A MAC address starting with 00:30:1B, 18:D9:EF, or 80:EE:73 belongs to Shuttle Inc., a Taiwan-based PC and embedded-systems manufacturer, typically seen on the onboard network interface of one of its barebone or industrial PC systems.

IEEE records three direct MA-L assignments to this company: 00:30:1B is filed as "SHUTTLE, INC." at a Taipei address, while 18:D9:EF and 80:EE:73 are filed as "Shuttle Inc." at a second Taipei address (No. 30, Lane 76, Rei Kuang Rd). The name/address split is ordinary registry drift across separate filing dates, not evidence of two companies — none of the three is a shared IEEE-RA block.

Shuttle Inc. is a real, decades-old manufacturer (founded 1983, headquartered in Taipei, with European/US/Japan offices) best known for its XPC mini/barebone PC line and, increasingly, for fanless industrial Box-PC and Panel-PC systems sold to OEMs/VARs for digital signage, POS, and similar embedded use. That product breadth plus three independent OUI assignments is the substance that clears this entry for a full vendor page rather than a bare-registration shell.

A separate, similarly-named IEEE registrant — "Space Shuttle Hi-Tech Co., Ltd." (00:16:2E) — is an unrelated Taiwanese company and maps to its own vendor slug; it is not part of this grouping and should not be merged with it.

IEEE's public OUI data (the IEEE MA-L registry) publishes no assignment date for any of these three prefixes. Third-party lookup sites show a "date registered" figure for 80:EE:73, but that is a database artifact of the aggregator, not an IEEE-published fact, and is not reproduced here.

IEEE assignments

00:30:1B → "SHUTTLE, INC.", Taipei, Taiwan; 18:D9:EF → "Shuttle Inc.", No. 30 Lane 76 Rei Kuang Rd, Taipei 114, Taiwan; 80:EE:73 → "Shuttle Inc.", same address as 18:D9:EF [Confirmed] — the IEEE MA-L registry (00301B, 18D9EF, 80EE73)

Registry / block size

MA-L (24-bit OUI) x3; direct assignments, not IEEE-RA sub-allocated blocks [Confirmed] — the IEEE MA-L registry

Device types

barebone/mini PCs (XPC line), industrial fanless Box-PC and Panel-PC systems [Confirmed] — https://www.shuttle.eu/en/about

Notable products

Related but distinct entry

00:16:2E → "Space Shuttle Hi-Tech Co., Ltd.", Hsinchu, Taiwan — different company, maps to vendor-space-shuttle-hi-tech, not this grouping [Confirmed] — the IEEE MA-L registry (00162E)

Registration date

not published by IEEE for any of the three prefixes; a third-party "date registered" value seen for 80:EE:73 is a database artifact, not an IEEE fact [Confirmed absence] — https://maclookup.app/macaddress/80EE73 (illustrates the artifact, not an authoritative date)

Security context

no Shuttle-specific CVE found; Shuttle shipped a January 2018 BIOS update for several XPC/embedded models addressing the industry-wide Intel ME/TXE microcode issue — standard OEM patch behavior, not a distinguishing flaw [Confirmed] — https://faq.shuttle.eu/faq:software:security

Analyst note

all three prefixes are direct, unshared MA-L assignments to Shuttle Inc. and reliably identify its hardware; do not conflate with the unrelated "Space Shuttle Hi-Tech Co., Ltd." registrant (00:16:2E), which is a different company under a different vendor slug.
