NetComm Limited — 2 prefixes (MA-L)

A MAC address starting with 00:40:28 or 00:60:64 belongs to NetComm Limited, an Australian telecommunications-equipment maker whose products in this era were dial-up modems, not a modern router or Wi-Fi device brand.

NetComm Limited first listed on the ASX on 21 December 1993 under ticker NTC. It briefly traded as Sirius Technologies Limited between 11 February 1998 and 6 December 1999 before reverting to the NetComm Limited name, then was renamed NetComm Wireless Limited on 22 December 2011 — a straight corporate rename, not an acquisition of an unrelated company.

Independent, non-registry sources document NetComm Limited-branded hardware catalogued under this registrant: the CARDMODEM GSM (CM3501), a PCMCIA modem/fax card with GSM I/O, and the INMODEM 336 (IN3410) analogue modem, both catalogued in the TULARC modem archive. No single source ties a specific model to a specific one of these two prefixes, so the device-class link is Likely rather than Confirmed at the model level.

This entry covers only the pre-2011 legal name "NETCOMM LIMITED" and its two MA-L assignments. The separately-tracked vendor-netcomm-wireless entry covers the same company's post-2011 name and its two later, distinct assignments (F8CA59, 18F145) — the two entries should not be merged, and prefixes should not cross over between them. A third assignment, 4435B9, is registered to the distinct registrant string "NetComm Wireless Pty Ltd," which slugifies separately and belongs to vendor-netcomm-wireless-pty, not to either entry here.

No security issue is known to attach specifically to 00:40:28 or 00:60:64. Router-firmware CVEs documented under the "NetComm" brand (CVE-2022-4873, CVE-2022-4874, CVE-2024-25290) affect router and mesh products documented well after the 2011 rename, and almost certainly ship under NetComm Wireless's newer OUI blocks rather than these two dial-up assignments, which predate the 2011 rename.
