MAC address vendor

SERVERCOM (INDIA) PRIVATE LIMITED — 11 prefixes (MA-L)

Primary prefix
28:A9:15
Block
MA-L
Status
Active

Summary

// what this is
Servercom is registered to MAC prefix 28:A9:15 and 10 more in the IEEE OUI database. When a device's MAC address begins with 28:A9:15, that block was registered by Servercom — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A SERVERCOM (INDIA) OUI = Sercomm-manufactured hardware, typically operator-supplied CPE sold under a third-party brand. Treat as ISP-grade CPE with a recurring-RCE risk profile; verify firmware currency. Do not confuse with Servers.com.

About this vendor.

Updated  ·  Confidence: High

"SERVERCOM (INDIA) PRIVATE LIMITED" holds 11 MA-L OUI blocks, all registered to E-43/1 Okhla Industrial Area Phase-II, New Delhi, IN. Despite the name, this is not the bare-metal hosting provider Servers.com (Nexcess); it is the New Delhi manufacturing subsidiary of Sercomm Corporation, the Taipei-based telecom-CPE maker incorporated in India on 2 December 2019. The blocks back the kind of equipment Sercomm builds and white-labels for ISPs worldwide: FTTx and broadband home gateways, DSL/FTTH/4G/5G fixed-wireless routers, Wi-Fi mesh extenders, DOCSIS modems, and IoT gateways — devices that typically reach end users as operator-supplied customer-premises equipment rather than under a Servercom-branded retail name. Two caveats matter for any work on this vendor. First, the name collision: "Servers.com" is an entirely separate hosting company with no IEEE OUI registration, and conflating the two is a real data-quality trap. Second, the security posture: Sercomm-family CPE has a documented CVE history, including a reactivatable backdoor in Sercomm-based modems (surfacing across Netgear/Cisco/Diamond-branded hardware), CVE-2021-44080 (authenticated root RCE on the SerComm h500s DSL gateway), and CVE-2025-67113 (unauthenticated OS command injection via the CWMP/ACS client on the SCE4255W) — the recurring-firmware-RCE profile of a widely deployed ISP CPE supplier. As always, the OUI identifies the manufacturer of the silicon/interface, not necessarily the brand on the box.

IEEE assignment
11 prefixes → SERVERCOM (INDIA) PRIVATE LIMITED, registered New Delhi, IN [Confirmed] — IEEE MA-L
Registry / block size
MA-L (24-bit OUI); holds 11 IEEE prefixes (~16.7M addresses each) [Confirmed] — IEEE MA-L, corroborated by udger.com / maclookup.app. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); the cached registry has no date field. Third-party "first seen" values (e.g. maclookup.app 2020-09-15) are database ingestion artifacts, not IEEE facts.

Typical deployment context
operator-supplied customer-premises equipment (home broadband gateways/routers white-labeled by telecom operators), plus enterprise Wi-Fi and IoT/smart-home contexts. FY2024 revenue ~₹1,550 Cr with ~24 employees indicates a manufacturing/distribution entity, not an end-user retail brand

Security context
Sercomm-family CPE has a documented vulnerability history — a reactivatable backdoor in Sercomm-based modems (Netgear/Cisco/Diamond-branded units); CVE-2021-44080 (authenticated root RCE via setup.cgi on the SerComm h500s, firmware lowi-h500s-v3.4.22, CVSS 6.6); CVE-2025-67113 (unauthenticated OS command injection via the CWMP client on the SCE4255W, exploitable by a malicious ACS)

Special note
HIGH name-collision risk. "SERVERCOM (INDIA) PRIVATE LIMITED" (this OUI registrant; a Sercomm subsidiary) is NOT "Servers.com" / "Servers.com by Nexcess," a US/EU bare-metal hosting provider (founded 2014, Lansing MI) that holds no IEEE OUI registration. Do not conflate them.
[Confirmed] — servers.com, tofler.in

Analyst note
A SERVERCOM (INDIA) OUI identifies Sercomm-manufactured hardware (typically ISP CPE), but the device is usually sold under an operator's or third party's brand, so the OUI names the maker, not the retail label. Treat any such device as ISP-grade CPE with a recurring-RCE risk profile and verify firmware currency.
