Which company owns MAC address prefix 10:95:4B?

MAC address prefix 10:95:4B is registered to Megabyte Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:95:4B has a network interface built by Megabyte Ltd..

What is the OUI 10:95:4B?

10:95:4B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Megabyte Ltd.. It covers every address from 10:95:4B:00:00:00 to 10:95:4B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-95-4B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:95:4B:00:00:00 that is 10:95:4B — 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 Megabyte Ltd. located?

Megabyte Ltd. is listed at Unit 507, 5/F, Building 12W, NO.12 Science Park Avenue, Hong Kong Science Park, Shatin, New Territories Hong Kong HK NA in the IEEE OUI registry entry for 10:95:4B.
