Hangzhou AlmightyDigit Technology Co., Ltd — 9C:1F:CA (MA-L)

Hangzhou AlmightyDigit Technology Co., Ltd holds a single IEEE MA-L block, 9C:1F:CA, which covers roughly 16.8 million addresses out of the 24-bit OUI assignment. The registry record places the company at Room A0041, 10/F, Building 1, Haizhi Center, Cangqian Street, Yuhang District, Hangzhou, Zhejiang 310000, China. Third-party OUI mirrors note the block was initially filed under the prior name "Hangzhou Quanneng Digital Technology Co.,Ltd" before being updated to the current English name — a detail consistent with a romanization/rename of the same Chinese entity. The company's consumer-facing brand appears to be QUAMROX, corroborated by two USPTO trademark filings whose goods classes list webcams, camcorders, intercoms, loudspeakers, microphones, audio and video receivers, and related AV peripherals; that trademark goods description is the only primary-source signal of what device categories carry this OUI. No official vendor website was located, no FCC filings surfaced under this name, and no CVEs, malware, botnet associations, or security advisories were found, so the OUI currently identifies a low-public-profile AV-peripheral maker rather than any documented security-relevant fleet. As always with MA-L records, IEEE publishes no assignment date — the 2022 dates shown by lookup mirrors are their own database artifacts, not IEEE facts, and are not recorded here as a registration date.

Analyst note

One MA-L block tied to a low-public-profile Chinese AV-peripheral maker (brand QUAMROX). The OUI plausibly fingerprints webcams/intercoms/speakers, but device categories rest solely on the trademark goods class, so treat asset-classification mappings as inferential rather than vendor-confirmed.
