DAEHAP HYPER-TECH — 3 prefixes (MA-L)

A MAC address starting with 00:26:A8, 78:46:C4, or 78:CB:68 identifies hardware from DAEHAP HYPER-TECH, a South Korean company registered in Seongnam, Gyeonggi-Do, that IEEE MA-L records show holding three separate OUI blocks. A direct fetch of the vendor's own English-language product pages confirms three device lines: an EFT-POS Terminal, a Smart Card Terminal, and a Taxi Meter Integrated POS Terminal.

Independent search-engine snippets separately describe the firm as also producing financial IC cards and membership cards. Those two categories are not documented on the vendor's own product pages reached in this pass, so they are carried as a secondary, lower-confidence claim rather than a vendor-site-confirmed device class.

Holding three distinct MA-L assignments under one registrant name is itself a substance signal - a bare shell registrant rarely holds multiple blocks. The three addresses on file (SK Techno-Park Mega Center #1108; Woolim Lions Valley 5-cha #A-805; Woolim Lions Valley 5-cha #A-810) sit in the same Sangdaewon-dong / Jungwon-Gu office-park area of Seongnam, consistent with one company at different suite numbers.

One registry row lists a US country code alongside a Korean-toponymy address (78:46:C4) - treated as a data-entry inconsistency in the IEEE record, not a second location. No first-party company-status source resolves for this registrant: a Crunchbase organization page exists but its content is not accessible, so org_status is Unknown.

No registration date is published by IEEE for any OUI; any third-party "date registered" figure is a database artifact, not an IEEE fact. No security advisories or device-specific incident reports were found for these prefixes; do not conflate with unrelated Dahua-brand CVEs that surface only on name-similarity searches.

IEEE assignment

3 prefixes → DAEHAP HYPER-TECH, registered Seongnam, Gyeonggi-Do, KR [Confirmed] — IEEE OUI Registry (the IEEE MA-L registry, lines 2123, 25923, 34443)

Registry / block size

MA-L (24-bit OUI) x3; no MA-M or MA-S assignments found under this name [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry (negative search)

HQ / country

Seongnam, Gyeonggi-Do, South Korea (Sangdaewon-dong / Jungwon-Gu office-park area; three suite addresses on file across the three OUIs) [Confirmed] — IEEE OUI Registry. The 78:46:C4 row carries a US country code with Korean-toponymy address text — a likely registry data inconsistency, not a second HQ [Unknown]

Company status

Unknown — no company-status source resolves for this registrant. A Crunchbase organization page exists at crunchbase.com/organization/daehap-hypertech but is not accessible (HTTP 403); no alternative first-party status source was found [Unknown] — crunchbase.com/organization/daehap-hypertech

Device types

EFT-POS Terminal (credit/debit card payment terminal with EMV IC-card support, embedded Linux, PSTN modem + Ethernet, EMV Level 1 & 2 certification), Smart Card Terminal, Taxi Meter Integrated POS Terminal [Confirmed] — direct fetch, daehap.koreasme.com/eng/product/product01_01.html, product02.html, product03.html (HTTP 200). Financial IC cards and membership cards are additionally described in independent search-engine snippets but are not documented on the vendor pages reached in this pass

Verified sample prefixes (all MA-L, DAEHAP HYPER-TECH)

00:26:A8, 78:46:C4, 78:CB:68 [Confirmed] — IEEE OUI Registry

Registration date

Unknown for all three OUIs — IEEE's public OUI data (the IEEE MA-L registry: Registry, Assignment, Organization Name, Organization Address) contains no assignment/registration date; any third-party "date registered" figure is a database-scrape artifact, not an IEEE fact

[Confirmed] — standards.ieee.org/products-services/regauth/oui/public.html

Special note

The 78:46:C4 registry row's US country code alongside a Korean address (Jungwon-Gu Seongnam) is inconsistent with the other two rows (both KR) and is treated as a registry data-entry artifact rather than evidence of a US presence [Unknown/flagged inconsistency]. The vendor's English-language product pages resolve via direct HTTP fetch and list EFT-POS Terminal, Smart Card Terminal, and Taxi Meter Integrated POS Terminal as product categories; financial IC cards and membership cards, mentioned only in search-engine snippets, remain a secondary-sourced claim, not vendor-confirmed. This entry supersedes an earlier candidate version of this file that asserted RFID and membership-card device types as [Confirmed] without a direct vendor-site fetch — this pass's own direct fetch found no RFID mention anywhere on the vendor's site, so that claim was dropped rather than carried forward.

Security history

no CVEs, security advisories, incident reports, or honeypot/fingerprint writeups found specific to these OUIs or to Daehap Hyper-Tech devices; a name-similarity search surfaces only unrelated Dahua-brand CVEs, which do not apply here [Confirmed absence in search] — n/a

Analyst note

Three separate IEEE MA-L assignments under one registrant name is a substance signal distinguishing this entry from a bare single-OUI shell, and is itself first-party (registry-sourced). The device class is now directly confirmed via the vendor's own site — EFT-POS, Smart Card, and Taxi Meter Integrated POS Terminal product lines, i.e. payment/POS hardware — while the financial-IC-card and membership-card claims remain secondary-sourced only.
