The IEEE registrant for this single MA-L block, 78:F2:76, is "Cyklop Fastjet Technologies (Shanghai) Inc.," registered at No 18, Lane 699, Zhang Wengmiao Rd, Fengxian district, Shanghai, China 201401 — the Chinese manufacturing/technology arm carrying the Cyklop brand, which is broader than the century-old European Cyklop packaging-automation group (founded 1912 in Cologne; group operations across Italy and the Netherlands). The "Fastjet" in the registrant name is the strongest device-type signal: Cyklop's coding-and-marking line markets continuous-inkjet (CIJ) and thermal-inkjet (TIJ) printers — product families such as the CM750, CM780, and CM600 — that carry Ethernet, USB, and RS232 connectivity for remote operation and integration into automated production and packaging lines. No public IEEE or vendor datasheet states exactly which device consumes this block, so the printer attribution is a strong inference from the registrant name plus the product catalog rather than a confirmed mapping. These are OT/ICS-class endpoints that typically live inside factory and warehouse networks rather than on the open internet. For triage, a 78:F2:76 address most plausibly belongs to a networked Cyklop industrial coding/marking printer on a production-line segment. No Cyklop-specific CVEs or security advisories were found; the general posture for network-enabled industrial printers (weak or absent management-interface authentication, legacy unencrypted protocols, slow patch cadence) is a sector-level concern, not a documented Cyklop disclosure.
- IEEE assignment
- 78:F2:76 → "Cyklop Fastjet Technologies (Shanghai) Inc." (Fengxian district, Shanghai, CN) [Confirmed] — IEEE MA-L (oui.csv, line 20)
- Registry / block size
- MA-L (24-bit OUI); one block on record (78:F2:76, ~16.7M addresses) [Confirmed] — IEEE oui.csv. NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.
- HQ / country
- No 18, Lane 699, Zhang Wengmiao Rd, Fengxian district, Shanghai, China 201401 (registry address) [Confirmed] — IEEE oui.csv. (Raw CSV shows "No 18?Lane 699"; the "?" is a character-encoding artifact in the cached file — the intended separator is a comma.)
- Company status
- active; the registrant is the Shanghai entity carrying the Cyklop brand. The broader Cyklop packaging-automation group is a 100+ year-old company (founded 1912, Cologne, Germany; current group operations HQ'd in Italy/Netherlands) [Confirmed for vendor brand; Shanghai-entity / parent-relationship specifics not independently confirmed] — cyklop.com, cyklop.com/company-history
- Device types
- industrial coding/marking printers — continuous-inkjet (CIJ) and thermal-inkjet (TIJ) models (CM750, CM780, CM600 lines) with Ethernet/USB/RS232 connectivity; part of Cyklop's broader packaging-automation range (strapping machines, stretch wrappers, tape dispensers). The OUI is most plausibly on the networked coding/marking printer, but no datasheet confirms which device uses the block [Likely] — needham-ink.com/cij-printers/cm750, needham-ink.com/thermal-inkjet-printers/cm600, shop.cyklop.com/collections/continuous-inkjet-printers
- Notable products
- CM750 / CM780 (CIJ), CM600 (TIJ) coding & marking printers (Cyklop / Cyklop Needham brand)
- Verified prefix
- 78:F2:76 (MA-L) [Confirmed] — IEEE oui.csv
- MA-M / MA-S
- none — no MA-M assignment in mam.csv and no MA-S (OUI-36) assignment in oui36.csv for "cyklop"; the single MA-L block is the complete registry record [Confirmed] — IEEE mam.csv, IEEE oui36.csv
- Network connectivity
- Cyklop coding/marking printers (CM750, CM600) expose Ethernet, USB, and RS232 for remote printing and production-line integration; TCP/IP is implied by Ethernet support, but specific services/port numbers are not publicly documented in available datasheets [Likely] — needham-ink.com/cij-printers/cm750, needham-ink.com/thermal-inkjet-printers/cm600
- Security context
- no Cyklop-specific CVEs or product security advisories found as of June 2026. As Ethernet-connected industrial inkjet/coding printers these are OT/ICS-class endpoints; the general risk profile for networked industrial printers in this class (weak/absent management-interface authentication, legacy unencrypted protocols such as FTP/Telnet/HTTP, minimal patch cadence) is a sector-level concern — industry analogues include CISA ICS advisory ICSA-19-232-01 and CVE-2021-3438. No evidence Cyklop devices have been specifically targeted; security posture is Unknown — no public disclosure found [Unknown] — cisa.gov/news-events/ics-advisories/icsa-19-232-01, sentinelone.com/labs/cve-2021-3438
- Third-party OUI corroboration
- no third-party OUI lookup result for "Cyklop" was retrievable via maclookup.app or oui.is during this pass; the assignment is sourced from the IEEE MA-L registry (oui.csv) and not independently corroborated by a third-party lookup tool [Likely — single-source (IEEE registry)] — maclookup.app/search/vendors, oui.is

- Analyst note
- A 78:F2:76 OUI maps to the Shanghai "Cyklop Fastjet Technologies" registrant; the "Fastjet" name plus the product catalog make a networked industrial coding/marking inkjet printer the most plausible device, though the specific device is not confirmed in public sources. Treat as OT/ICS production-line equipment, and keep the China registrant distinct from the European Cyklop packaging group's corporate identity.
