Icotera A/S — 3 prefixes (MA-L)

A MAC address beginning 4C:C4:49, 00:0F:15, or 00:1E:80 belongs to Icotera A/S, a Danish manufacturer of fibre broadband customer-premises equipment — typically seen on ISP-issued ONTs, fibre gateways, and Wi-Fi routers deployed in residential FTTH (fibre-to-the-home) networks across Europe.

Icotera holds three separate IEEE MA-L (24-bit) OUI blocks, all registered to the same Vibeholms Allé 12, Brøndby, Denmark address — an unusually broad footprint for a company its size, and enough to distinguish it from a bare single-OUI shell registration. The company's official site confirms it as an active, substantive manufacturer founded 2007, shipping named product lines including the IGW3000 and i6850 routers, i5800/i5200 residential ONTs, and the i740x XGS-PON series, with releases continuing into 2024-2025 (Baldur PON, Saga Wi-Fi 7).

IEEE's public OUI data publishes no assignment or registration date for any of the three blocks, so none is recorded here. No CVE or documented vulnerability specific to Icotera hardware was found — that is reported as unknown/not found, not as a confirmed absence of vulnerabilities. Icotera does maintain a formal vulnerability disclosure policy and a PSIRT contact address.
