What is the OUI 48:9D:24?

48:9D:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BlackBerry RTS. It covers every address from 48:9D:24:00:00:00 to 48:9D:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-9D-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:9D:24:00:00:00 that is 48:9D:24 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is BlackBerry RTS located?

BlackBerry RTS is listed at 451 Phillip Street Waterloo ON CA N2L 3X2 in the IEEE OUI registry entry for 48:9D:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
