Raisecom Technology CO., LTD — 2C:B6:C8 (MA-L)

The OUI 2C:B6:C8 is an IEEE MA-L (24-bit) block assigned to Raisecom Technology CO., LTD, a Beijing-based B2B telecom-infrastructure manufacturer founded in 1999. The registry address (No. 11, East Area, No. 10 Block, East Xibeiwang Road, Beijing 100094, China) matches the vendor's published headquarters. Raisecom builds carrier and enterprise networking gear rather than consumer devices: optical transport (OTN/PTN), xPON access equipment (OLTs/ONUs), carrier and industrial Ethernet switches, multi-service access platforms (MSAP), smart residential gateways, and small-cell base stations. Third-party aggregators list 2C:B6:C8 among roughly 13 MA-L prefixes the company holds, so a single consolidated vendor entry is more useful than per-prefix pages. Two operational caveats matter for anyone classifying hardware under this OUI. First, no registration date is recorded: IEEE publishes no allocation dates for OUI/MA-L blocks, and the 2022-06-25 date shown on third-party tools is a database artifact, not an IEEE fact. Second, the security posture is poor — two critical CVEs are on record (an unauthenticated SSH/root bypass on RAX701 switches and a command-injection flaw across the MSG gateway line), CISA issued an ICS advisory, and the vendor was documented as non-responsive to coordinated disclosure. Devices presenting this OUI should be treated as elevated-risk network infrastructure.

Registration date

Unknown — IEEE publishes no registration/allocation date for OUI/MA-L blocks; the local registry CSV has no date field. Third-party tools show 2022-06-25, which is a database artifact, NOT an IEEE fact — do not surface it as an IEEE registration date.

[Unknown] — IEEE the IEEE MA-L registry (no date column); maclookup.app

Device types

carrier/enterprise networking and telecom infrastructure — OTN/PTN optical transport, xPON access (OLT/ONU), carrier and industrial Ethernet switches, multi-service access platforms (MSAP), smart residential gateways, small-cell base stations. No consumer devices. Specific device line for the 2C:B6:C8 block is Unknown (per-OUI device mapping is not published).

Security note

HIGH RISK. CVE-2025-11534 (CVSS 9.8) — unauthenticated SSH/root bypass on RAX701-GC-WP-01 switches (firmware P200R002C52/C53) via TCP 10022/830; no patch at disclosure; vendor non-responsive to CISA coordination. CVE-2024-7120 (Critical) — remote command injection across MSG1200/MSG2100E/MSG2200/MSG2300 (firmware 3.90); ~25,000 devices exposed at disclosure. CISA ICS advisory ICSA-25-294-06 issued.

Analyst note

A 2C:B6:C8 address on a globally-administered MAC identifies genuine Raisecom infrastructure gear. Given two critical CVEs and a documented non-responsive disclosure history, hosts under this OUI warrant elevated scrutiny in asset inventory and exposure scans.
