Xiamen IPRT Technology Co., Ltd. holds the IEEE MA-L block B8:FB:AF, registered to "Xiamen IPRT Technology CO.,LTD" at Huili Industry Park, Meixi Road, Tongan District, Xiamen, Fujian, China. IPRT is a manufacturer of thermal printing hardware — desktop label printers (BY-243, BY-245, BY-480 series), portable and mini thermal printers (the L12 mini), thermal receipt printers, and Android POS systems — and it markets much of this catalog under the paired "IPRT BEEPRT" brand. The block is the IEEE-assigned hardware identifier for these devices. Connectivity in the FCC-filed models is Bluetooth-first: every certified unit operates in the 2.4 GHz ISM band (2402–2480 MHz) under FCC Part 15C as a digital transmission system, filed under grantee code 2A2HA, and some product listings additionally advertise Wi-Fi. For classification purposes a B8:FB:AF prefix points to an IPRT-built thermal printer or POS peripheral. No IPRT-specific security advisories or CVEs were found; the security picture is the generic one for Bluetooth/Wi-Fi printer peripherals — pairing weaknesses, in-proximity print-data exposure, and, for any networked Wi-Fi model, the standard raw-print (9100) / IPP (631) exposure if misconfigured. IEEE publishes no registration date for OUI assignments, so the allocation date is genuinely unknown rather than fabricated.
- IEEE assignment
- B8:FB:AF → Xiamen IPRT Technology CO.,LTD [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv line 571)
- Registry / block size
- MA-L (24-bit OUI; ~16.7M addresses) [Confirmed] — IEEE MA-L. Entry appears only in oui.csv (MA-L); not in mam.csv (MA-M) or oui36.csv (MA-S).
- Registered address
- 3~5 Floor, No.101, Huili Industry Park, Meixi Road, Tongan District, Xiamen, Fujian CN 361000, China [Confirmed] — IEEE MA-L
- HQ / country
- Xiamen, Fujian Province, China [Confirmed] — exporthub.com directory, fccid.io filings
- Allocated date
- Unknown — IEEE publishes no registration/assignment dates for OUI/MA-L blocks; none present in the registry file. Any "date registered" on third-party MAC lookup tools is a database artifact, not an IEEE fact. [Unknown] — IEEE Registration Authority (standards.ieee.org/products-programs/regauth/)
- Company status
- active [Likely] — exporthub.com, Alibaba storefront (iprint.en.alibaba.com)
- Device types
- thermal barcode/label printers, portable & mini thermal printers, thermal receipt printers, Android POS systems [Confirmed] — fccid.io (2A2HA filings), alibaba.com product listings
- Notable products
- BY-243 / BY-245 / BY-480 label-printer series, L12 mini label printer, JD-328 / JD-468 portable printers [Confirmed] — fccid.io/2A2HA-BY-245BT, fccid.io/2A2HA-JD-328BT, fccid.io/2A2HA-L12, fccid.io/2A2HA-JD-468BT
- Wireless connectivity
- Bluetooth (primary; 2.4 GHz ISM 2402–2480 MHz, FCC Part 15C DTS, grantee 2A2HA); some listings also advertise Wi-Fi. Sub-1 mW conducted output; no Ethernet/IP interface evidenced in reviewed FCC filings. [Confirmed for Bluetooth; Wi-Fi Likely] — fccid.io/2A2HA-BY-245BT, fccid.io/2A2HA-JD-328BT, fccid.io/2A2HA-L12
- Certifications
- ISO 9001, ISO 14001, CCC (3C), RoHS, CE; FCC Part 15C (grantee 2A2HA) [Confirmed for FCC; ISO/CE/3C Likely] — exporthub.com, fccid.io/2A2HA-BY-245BT
- Vendor site
- http://en.iprt.com.cn/ (unreachable / connection refused at research time); Alibaba storefront iprint.en.alibaba.com [Likely] — en.iprt.com.cn, iprint.en.alibaba.com
- Brand relationship
- IPRT and BEEPRT appear as a dual-brand pairing on shared Alibaba product pages; a separate "Xiamen Beeprt Information Technology Co., Ltd." Alibaba page exists with near-total product overlap. Same legal entity vs. sister company is not publicly confirmed. [Likely] — alibaba.com (IPRT BEEPRT listings), beeprint.en.alibaba.com
- Founding context
- established 2015 per B2B directory listings; claimed ~42-person R&D team, 12 production lines, ~11,000 m² factory [Likely] — exporthub.com (single B2B-directory source; self-reported figures)
- Security note
- no IPRT-specific CVEs, advisories, or exploit disclosures found. Generic Bluetooth/Wi-Fi printer-peripheral risk applies categorically (pairing weaknesses, in-proximity print-data exposure; raw-print 9100 / IPP 631 exposure for misconfigured networked models) but is not documented for IPRT devices specifically. [Likely] — shadowserver.org (open-IPP report), asimily.com (printer IoT risks)
- Analyst note
- a B8:FB:AF prefix reliably identifies IPRT-built thermal-printer / POS hardware; most units are Bluetooth peripherals rather than IP-networked endpoints, so network-side exposure is limited to Wi-Fi-capable models.
