What is the OUI 54:70:68?

54:70:68 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to VTech Communications Limited. It covers every address from 54:70:68:00:00:00 to 54:70:68:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-70-68.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:70:68:00:00:00 that is 54:70:68 — 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 VTech Communications Limited located?

VTech Communications Limited is listed at 23/F, Tai Ping Industrial Centre, Block 1, 57 Ting Kok Road, Tai Po, New Territories Hong kong HK 00852 in the IEEE OUI registry entry for 54:70:68.
