About this vendor.

MAC addresses beginning with 00:15:9D or 00:06:67 match IEEE MA-L assignments listing the registry organization name Tripp Lite. The assignments do not identify a specific device or device category. Product and industry information: Unknown.

Each prefix fixes the first 24 bits of a 48-bit MAC address, leaving 24 suffix bits, or 16,777,216 possible suffix values per prefix. This is a mathematical address space, not a count of devices, shipments, or addresses in use. Both prefixes have Group bit 0 and Local bit 0 in their first byte. Those bit values are fixed for an exact prefix match; changing either bit produces a different prefix.

A matching capture can establish that its initial 24 bits correspond to a Tripp Lite registry assignment. It cannot establish the product, current operator, deployment, prevalence, or security state. The IEEE CSV records show no assignment dates. RFC 7042 describes 48-bit MAC identifiers as a prefix followed by additional bits and explains the Group and Local bit significance.
