Shenzhen Comnect Technology Co.,LTD — 2 prefixes (MA-L)

A MAC address starting with 30:53:5B or 4C:2E:FE belongs to Shenzhen Comnect Technology Co.,LTD, a Shenzhen, Guangdong-based OEM/ODM manufacturer typically seen on SOHO/SMB networking gear — xDSL/ADSL modems, GPON ONT units, wireless routers, switches, powerline adapters, and IP cameras.

Both blocks are registered under the same legal name at Shenzhen facility addresses (Nanshan District, postal code 518055), one at Shenzhen International Innovation Valley and one at Baisha High-Tech Park. This dual registration under one name is what separates the entry from a bare single-OUI shell.

A third, similarly-named MA-L prefix, 4C:6E:6E, is registered to "Comnect Technology CO.,LTD" — no "Shenzhen" in the legal name, and a different address (Xinyuan Industrial Park). It is treated here as a separate registrant, not folded into this vendor's prefix list; any affiliation between the two names is unconfirmed.

Third-party company profiles (a storefront, a company directory listing, and a market-data page) describe the vendor as founded in 2012, shipping networking and communication products to dozens of countries, with ISO 9001/14001/45001 certification claimed. These are single-source aggregator claims, not independently corroborated, so they carry a Likely rather than Confirmed tag.

No CVE, security advisory, or documented default-credential issue tied to Comnect-branded hardware was found in an August 2026 search. That is a sourced negative, not a clean-record confirmation — the company appears to operate as a white-label ODM, so downstream vulnerabilities in rebranded products may surface under an OEM or ISP's name rather than "Comnect."
