Logic Replacement Tech. Ltd. — 2 prefixes (MA-L)

Logic Replacement Tech. Ltd. is a UK-registered IEEE MA-L (OUI-24) holder with two blocks: 00:60:86 and 02:60:86, both assigned to the same organization at 14 Arkwright Road, United Kingdom. The two blocks are confirmed against the cached IEEE registry export and corroborated by third-party MAC lookups. Beyond the registry rows the company has almost no discoverable web presence — no vendor website, product line, or device category could be located, and no UK Companies House filing was found under the exact name. The 02:60:86 block is notable: its first octet (0x02) has the locally-administered bit set, which is atypical for a standard globally-administered OUI assignment and means addresses derived from it can collide with locally-generated or randomized MACs. The practical takeaway is that 00:60:86 reliably identifies this registrant's hardware, but device-type attribution for either block is unverifiable from public sources. Any "registration date" shown by third-party lookup tools (e.g. 2000-11-09) is a database artifact — IEEE publishes no OUI assignment dates.

IEEE assignment

2 prefixes → LOGIC REPLACEMENT TECH. LTD. (00-60-86 and 02-60-86) [Confirmed] — IEEE MA-L; the IEEE MA-L registry (Registry=MA-L, Assignments 006086 and 026086)

Registry / block size

MA-L (24-bit OUI); two blocks (~33.6M addresses combined) [Confirmed] — IEEE MA-L, https://www.macvendorlookup.com/api/v1/006086, https://maclookup.app/vendors/logic-replacement-tech-ltd

HQ / country

Registration date

Unknown — IEEE publishes no OUI assignment dates; third-party 2000-11-09 is a database artifact, not an IEEE fact [Unknown] — https://maclookup.app/vendors/logic-replacement-tech-ltd

Company status

Unknown — no UK Companies House filing found under "Logic Replacement Tech Ltd" / "Logic Replacement Tech" [Unknown] — https://find-and-update.company-information.service.gov.uk/search?q=Logic+Replacement+Tech

Device types

Unknown — no product descriptions, device types, or hardware categories found in any source [Unknown] — no source located

Vendor website

Unknown — no active or archived vendor website located [Unknown] — no source located

Verified prefixes (both MA-L, same org/address)

00:60:86, 02:60:86 [Confirmed] — IEEE MA-L / the IEEE MA-L registry

Not found in

MA-M (the IEEE MA-M registry) and MA-S (the IEEE MA-S registry) — no entries for this org [Confirmed] — the cached registry snapshots

Special note

02:60:86 has the locally-administered bit set on the first octet (0x02). This is atypical for a standard globally-administered OUI and means addresses from this block can overlap locally-generated/randomized MACs; no source explains why this block was issued/used this way

[Likely] — IEEE OUI structure; bit observed in the prefix itself

Security context

Unknown — no CVEs, threat-intelligence reports, or security advisories referencing this vendor or its OUI blocks were found [Unknown] — no source located

Analyst note

00:60:86 reliably identifies this registrant's hardware; the 02:60:86 block's locally-administered bit makes it weaker for asset attribution, and device-type identification is not possible from public data.
