Syrotech Networks. Ltd. — 3 prefixes (MA-L)

A MAC address beginning with 38:94:E0, 54:47:E8, or 7C:A9:6B belongs to Syrotech Networks. Ltd., a Hong Kong-registered manufacturer whose hardware shows up almost exclusively on GPON/EPON fiber-to-the-home equipment: ONUs, ONTs, OLTs, and WiFi routers sold under the Syrotech brand to ISPs, mostly in the Indian FTTH market.

IEEE's the IEEE MA-L registry lists three separate MA-L (24-bit) blocks under the identical registrant name and Tuen Mun, Hong Kong address — a real substance signal, since a bare shell registration typically holds only one block. No MA-M or MA-S sub-allocations exist for this organization.

The Syrotech brand is corroborated independently across B2B trade listings (Alibaba, IndiaMART, TradeIndia, Volza export records) naming specific SKUs such as the SY-GPON-1110-WDONT router and SY-GPON-1000R-ONT. Two formally assigned CVEs (CVE-2024-41690, CVE-2024-41686) target the SY-GPON-1110-WDONT's firmware, alongside additional findings from a Redfoxsec advisory covering credential exposure, command injection, and CSRF.

One caveat worth flagging: the OUI registrant, "Syrotech Networks. Ltd." at a Hong Kong address, is a distinct legal entity from GOIP Global Services Pvt. Ltd. (Noida, India), which already holds a separate DONE OUI vendor entry in this repo and describes itself on its own site as having established the "Syrotech Networks" brand. No corporate filing was found confirming these are the same company or a parent/subsidiary pair, so the two OUI registrations are treated here as related but not merged.

Security context

CVE-2024-41690 (plaintext credential storage, CVSS 4.6) and CVE-2024-41686 (weak password-policy enforcement, CVSS v4 7.3), both against SY-GPON-1110-WDONT firmware v3.1.02-231102; additional command-injection, CSRF, and default-Telnet-credential findings per a non-CVE Redfoxsec advisory [Likely] — securityvulnerability.io/vulnerability/CVE-2024-41690, github.com/advisories/GHSA-phh7-8q4v-gv55, redfoxsec.com/blog/security-advisory-multiple-vulnerabilities-in-syrotech-router

Entity relationship caveat

shares the "Syrotech" brand name with vendor-goip-global-services-pvt (GOIP Global Services Pvt. Ltd., Noida, India — a separate IEEE registrant/address, already a DONE entry in this repo); no corporate filing found confirming a single legal entity or parent/subsidiary relationship

[Likely] — syrotech.com/about, volza.com company profile, /mac/vendor/goip-global-services-pvt/

Special note

IEEE's public the IEEE MA-L registry publishes no registration date for any of the three prefixes; maclookup.app shows three different third-party "registered" dates per prefix under the same registrant, which are database-ingestion artifacts, not IEEE facts, and are not recorded here

[Confirmed] — the IEEE MA-L registry, maclookup.app

Related vendors

GOIP Global Services Pvt. Ltd. (related "Syrotech" brand, separate OUI registrant; see caveat above)

Analyst note

Three dedicated OUI blocks plus a corroborated, currently-selling FTTH product line indicate a real manufacturer, not a shell registration. Known CVEs against SY-GPON-1110-WDONT firmware make any Syrotech-branded router a candidate for firmware/credential review. Do not treat this Hong Kong registrant as the same company as the separately-registered GOIP Global Services Pvt. Ltd. (Noida, India) absent further confirmation, even though both trade under the "Syrotech" name. [Likely]
