BaudTec Corporation — 2 prefixes (MA-L)
Summary
- // what this is
- BaudTec is registered to MAC prefix
00:13:33and 1 more in the IEEE OUI database. When a device's MAC address begins with00:13:33, that block was registered by BaudTec — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both 00:13:33 and 94:46:96 are direct, standalone MA-L assignments to BaudTec — not shared IEEE-administered bases — so a MAC on either prefix reliably indicates BaudTec-made CPE. Default admin/admin credentials documented on at least one shipped model are a real hardening concern for anyone auditing devices carrying this OUI.
About this vendor.
A MAC address beginning with 00:13:33 or 94:46:96 belongs to BaudTec Corporation, a Taiwanese networking-equipment manufacturer, typically found on consumer and small-business ISP-bundled hardware — wireless ADSL2+/VDSL2 routers, USB ADSL modems, and Homeplug powerline adapters.
BaudTec holds two independent IEEE MA-L assignments (00:13:33 and 94:46:96), both registered to the same Hsichih (Xizhi), New Taipei City address. Unlike shared IEEE-administered bases such as 70:B3:D5, both blocks are direct, standalone /24 grants to BaudTec alone, so no shared-base caveat applies to either prefix.
The company is a genuine, identifiable manufacturer rather than a bare registration: it markets branded ADSL2+/VDSL2 routers and modems — for example the RN243R4-2T2R, an 802.11n router built on a Realtek RTL8672 SoC with FCC ID XKR-RN243R4 — operates the domain baudtec.com.tw, and holds registered trademarks including BAUDTEC and BAUDCOM.
On the security side, the RN243R4-2T2R is documented shipping with default web-admin credentials admin/admin — a real device-hardening concern for anyone identifying this OUI on a network. No CVE is recorded in the NVD for BaudTec as of an August 2026 search. A separate report tying a Baudtec-branded router to a 2014 academic XSS/CSRF disclosure could not be independently verified from readable primary-source text and is not asserted as fact here.
