MAC address vendor

A Brand New World in Sweden AB — 00:05:39 (MA-L)

Primary prefix
00:05:39
Block
MA-L

Summary

// what this is
A Brand New World in Sweden AB is registered to MAC prefix 00:05:39 in the IEEE OUI database. When a device's MAC address begins with 00:05:39, that block was registered by A Brand New World in Sweden AB — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Despite a single OUI assignment, this is a well-corroborated, identifiable formerly-public company with a specific product/business context (802.11b-class wireless-broadband infrastructure for internet access operators) rather than a bare shell registration. The company is most likely long defunct as an independent entity, so any 00:05:39-prefixed device encountered today is almost certainly legacy/decommissioned hardware from the early-2000s wireless-broadband era.

About this vendor.

Updated  ·  Confidence: Medium

A Brand New World in Sweden AB holds a single confirmed IEEE MA-L block, 00:05:39, registered to a Kista, Sweden address given only as "Box 1223" in the cached IEEE registry row (the row is truncated/malformed and drops the rest of the postal address). Read on the registry row alone this would look like a bare shell registration, but this is one of the stronger-corroborated single-OUI entries encountered in this pass: "A Brand New World in Sweden AB (publ)" was a publicly listed Swedish technology company, founded in 1994 and headquartered in Kista (Stockholm's telecom/IT cluster), with roughly 139 employees at its peak and operations extending into Norway, Denmark, Poland, Germany, Switzerland, France, China, and South Korea. Its business was developing and marketing infrastructure systems and products enabling mobile/wireless internet access — specifically wireless broadband equipment letting small offices, home offices, and households connect at speeds up to 11 Mbps, sold to local, regional, and national broadband network operators. An 11 Mbps ceiling is the hallmark data rate of 802.11b-class equipment, consistent with the company operating in the fixed-wireless-broadband/WLAN-infrastructure space in the 2000–2002 window. The company's shares traded on Nya Marknaden (a growth-company segment of the OM Stockholm exchange); it ran into financial trouble in 2001 (monthly cash burn falling from roughly SEK 17 million in January to SEK 10 million in March under a cost-cutting plan), was restructured, and was ultimately acquired by Wireless House AB (publ) via a share/convertible exchange offer accepted by more than 90% of ABNW's shareholders and convertible-holders; it was delisted from Nya Marknaden effective January 31, 2002. The company therefore appears to no longer exist as an independent operating entity, though its current formal status in the Swedish companies register (Bolagsverket) was not directly verified in this pass. A limitation worth flagging honestly: the primary-source Cision press releases describing all of this returned HTTP 403 when fetched directly in this pass, so these corporate-history claims rest on search-engine-synthesized snippets of those releases rather than a first-party document read, and are tagged [Likely] rather than [Confirmed] accordingly. No second OUI assignment under this exact legal name was found anywhere in the cached IEEE registry data (MA-L, MA-M, or MA-S).

OUI / registry class
00:05:39, MA-L [Confirmed] — the IEEE MA-L registry, cross-referenced the Wireshark manufacturer database (line 1351, short name "ABrandNewWor")
Organization name / OUI identity cross-check
"A Brand New World in Sweden AB" resolved identically by IEEE the IEEE MA-L registry, macvendors.com API, and udger.com [Confirmed — three independent angles agree] — the IEEE MA-L registry, https://api.macvendors.com/00:05:39:00:00:00, https://udger.com/resources/mac-address-vendor-detail?name=a_brand_new_world_in_sweden_ab
Organization address
registry row truncated/malformed, showing only "Box 1223 SE" with the street/postal-code portion dropped; udger.com's independent copy of the same registry data shows the identical truncation ("Box 1223", no further detail) [Confirmed as a shared data-source artifact, not a fuller address recovered] — the IEEE MA-L registry, https://udger.com/resources/mac-address-vendor-detail?name=a_brand_new_world_in_sweden_ab
Date registered
Unknown / null — IEEE's public OUI registry (the IEEE MA-L registry) publishes no assignment/registration date column, and neither macvendors.com nor udger.com displayed one either; nothing fabricated or attributed to IEEE [Confirmed] — the IEEE MA-L registry (schema), https://udger.com/resources/mac-address-vendor-detail?name=a_brand_new_world_in_sweden_ab
IANA Reference
not applicable — blank; this is an IEEE MAC/OUI assignment, not an IANA-administered registry [Confirmed]
Company identity / history
"A Brand New World in Sweden AB (publ)," founded 1994, HQ in Kista, Sweden; ~139 employees; international operations in Norway, Denmark, Poland, Germany, Switzerland, France, China, and South Korea; shares traded on Nya Marknaden (OM Stockholm exchange) [Likely — corroborated via search-engine-synthesized snippets of Cision (news.cision.com) press releases that returned HTTP 403 on direct fetch in this pass, not a first-party document read] — https://news.cision.com/se/a-brand-new-world (listing page), https://news.cision.com/se/a-brand-new-world/r/bolagsstamma-i-a-brand-new-world-in-sweden-ab--publ-,c41162
Business / product context
developed and marketed systems/products for wireless-broadband infrastructure enabling mobile internet access, up to 11 Mbps (802.11b-class speed), sold to local/regional/national broadband network operators building wireless-broadband access networks [Likely — same 403-blocked/search-snippet caveat as above] — https://news.cision.com/se/a-brand-new-world/r/a-brand-new-world-far-order-till-ett-varde-av-22-msek,c33355 (order press release, title only fetched via search; body not directly read)
Corporate end-state
restructured in 2001 amid declining cash reserves; acquired by Wireless House AB (publ) via share/convertible exchange accepted by >90% of ABNW shareholders/convertible-holders; delisted from Nya Marknaden effective 2002-01-31 [Likely — same 403-blocked/search-snippet caveat] — https://news.cision.com/se/a-brand-new-world/r/erbjudandet-fran-wireless-house-godtogs-av-abnw-s-aktieagare-och-konvertibelagare,c52933, https://news.cision.com/se/a-brand-new-world/r/omstrukturering-av-a-brand-new-world,c50855
Current legal/registry status
not directly verified in this pass — no current Bolagsverket/allabolag.se/ratsit.se record was found under this exact legal name; the company most plausibly ceased independent existence after the 2001–2002 Wireless House acquisition, but that is an inference from the historical record, not a confirmed present-day registry lookup [Unknown]
Additional OUI assignments under identical entity
none found — single MA-L block only; no matches for this org or OUI in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S) [Confirmed via registry scan] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry
Company substance
identifiable, formerly publicly-traded Swedish technology company with a specific, named product/business context (wireless-broadband/mobile-internet infrastructure equipment) and multi-country operations, corroborated across multiple independent Cision press-release titles/snippets and cross-referenced OUI-lookup services — this clears the "identifiable company with product/device context" bar despite holding only a single OUI; it is not a bare, anonymous single-OUI shell registration. Caveat: it is now most likely a defunct/absorbed entity (last confirmed activity 2001–2002), and the underlying press-release detail was read via search-engine snippets rather than direct fetch (403s on news.cision.com) [Likely] — https://news.cision.com/se/a-brand-new-world, https://udger.com/resources/mac-address-vendor-detail?name=a_brand_new_world_in_sweden_ab
Security context
no OUI-specific CVEs or abuse patterns surfaced in this pass; not exhaustively searched, and the company's hardware (circa-2000 802.11b-class fixed-wireless-broadband gear) is long past any active vendor-support lifecycle [Unknown]
