Maipu Communication Technology Co., Ltd. — 2 prefixes (MA-L)

Maipu Communication Technology Co., Ltd. is a Chinese enterprise- and carrier-networking equipment manufacturer founded in 1993 and headquartered in Chengdu's high-tech zone, Sichuan, China. The vendor holds two distinct IEEE MA-L (24-bit OUI) blocks — CC:D8:1F and 4C:C8:44 — both registered to the same legal name and the same Chengdu address (No.16 Jiuxing Avenue, Hi-tech zone, postcode 610094). Maipu's catalogue spans routers (core, aggregation, access, and 4G/5G M2M), Layer-2/Layer-3 and data-center switches, industrial switches, Wi-Fi access points, security firewalls and UTM appliances, GPON OLT/ONU gear, VoIP (SIP servers, IP-PBX, IP phones), and optical transceivers, deployed across telecom, banking, government, energy, and manufacturing sectors in 60-plus countries. A common data trap: the prefix 00:01:7A near Maipu in registry searches belongs to a *different* legal entity, "Chengdu Maipu Electric Industrial Co., Ltd.," at a different address — do not fold it into this vendor. As with all OUI work, IEEE publishes no registration date for MAC prefixes; the "2018-11-24" and "2022-12-01" dates surfaced by third-party MAC-lookup tools are database-scrape artifacts, not IEEE facts, and must not be presented as registration dates.

IEEE assignment

2 prefixes → Maipu Communication Technology Co.,Ltd., registered Chengdu, Sichuan, CN [Confirmed] — IEEE MA-L (lines 16125, 31978)

Registry / block size

Company scale

over 1,500 employees (~50% in R&D); CMMI Maturity Level 5; ISO 9001/14001/27001/45001; CE-EMC, FCC marks; 1,500+ patents filed (80%+ invention patents) [Confirmed] — maipu.com/GuanYu/

Security context

No CVEs or public exploits specific to Maipu devices found in this pass; no Maipu-specific government bans or sanctions identified. Maipu is NOT named on the FCC Covered List in available sources, though a broad 2026 FCC restriction on foreign-made (predominantly Chinese) routers targets vendors such as TP-Link. As a Chinese-origin infrastructure vendor, general geopolitical supply-chain considerations apply for sensitive Western government/defence deployments.

Analyst note

A globally-administered CC:D8:1F or 4C:C8:44 address reliably identifies genuine Maipu hardware for asset classification; absence of one does not prove "not Maipu" (devices can use third-party NICs or randomized MACs). OUI alone is not a substitute for device fingerprinting in inventory or access control.
