What is the OUI 10:4D:15?

10:4D:15 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Viaanix Inc. It covers every address from 10:4D:15:00:00:00 to 10:4D:15:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-4D-15.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:4D:15:00:00:00 that is 10:4D:15 — 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 Viaanix Inc located?

Viaanix Inc is listed at 434 N Main St. Wichita KS US 67202 in the IEEE OUI registry entry for 10:4D:15. This is the address the organization registered with the IEEE, which may differ from its current operating address.
