Gallagher Group Limited MAC prefixes: vendor identified, device unknown

A MAC address beginning with C0:6B:C7 or 00:90:1D matches an IEEE MA-L assignment to Gallagher Group Limited; it does not identify a specific device. The IEEE records show two 24-bit prefixes assigned to that exact legal name. Assignment dates are unavailable in these IEEE CSV records.

Each prefix covers 24 bits, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix. That is a range of possible address values, not a count of devices, shipments, or observed traffic. A matching address establishes the prefix match and registry assignment only.

For both prefixes, the first octet has the Group bit clear and the Local bit clear. These fixed bits follow from the literal prefixes; changing either bit produces a different prefix. RFC 7042 explains the Group and Local bit roles and how EUI-48 identifiers use an initial OUI or longer prefix followed by remaining bits.

Gallagher’s catalog lists software offerings including Command Centre, Mobile Credentials, Care Plan, Site Plans and Reporting, and REST API products, and presents them in a security products context that includes access control. The catalog does not map those products or device categories to either MAC prefix.

Vendor match

Gallagher Group Limited is the organization named in both IEEE MA-L assignments. [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv

Device identification

No specific device category is established for these prefixes. [Unknown] — https://standards-oui.ieee.org/oui/oui.csv

Prefix matching

Match the first 24 bits for either listed prefix; the remaining 24 bits are suffix space. [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv

Group and Local bits

Both prefixes have the Group bit and Local bit clear in the first octet. [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
