NST Audio Ltd — DC:96:2C (MA-L)

A MAC address starting DC:96:2C belongs to NST Audio Ltd, a UK-based manufacturer of professional and commercial audio equipment, and typically appears on Dante-networked digital signal processors used in touring and fixed-installation audio systems.

NST Audio Ltd holds a single verified IEEE MA-L block (DC:96:2C); no additional MA-M or MA-S assignment was found under the company name in the cached OUI, MAM, or 36-bit registries. UK Companies House lists the company (no. 08900388) as active, incorporated 18 February 2014, under SIC codes for electronic-component and electrical-equipment manufacturing.

The company's product line, documented on nstaudio.com, includes the DM88 System Processor, D48X Matrix Signal Processor, VMX88/VMX88L and VMO16 installation audio processors, and the ID48X Installation Matrix Signal Processor, several of which advertise built-in Dante audio-over-IP networking — genuine networked hardware consistent with holding an Ethernet OUI block.

The IEEE registry's address for DC:96:2C (32 Whitewall, Norton, North Yorkshire) differs from Companies House's current registered office (Malton, North Yorkshire); Norton and Malton are adjacent towns, so this likely reflects the same small company at different points in time rather than a mismatch, though that continuity was not independently confirmed.

A separate company, NST Technology Limited Co., Ltd., registered in Wuxi, Jiangsu, China, holds an unrelated MA-M block (assignment key 70F8E77). No corporate relationship between the two organizations has been verified; they are treated here as distinct entities that happen to share the initials NST. No CVE for NST Audio or its named products is recorded in the NVD as of an August 2026 search.
