Which company owns MAC address prefix B8:A4:4F?

MAC address prefix B8:A4:4F is registered to Axis Communications AB in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:A4:4F has a network interface built by Axis Communications AB.

What is the OUI B8:A4:4F?

B8:A4:4F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Axis Communications AB. It covers every address from B8:A4:4F:00:00:00 to B8:A4:4F:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-A4-4F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:A4:4F:00:00:00 that is B8:A4:4F — 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 Axis Communications AB located?

Axis Communications AB is listed at Emdalavägen 14 LUND SE 22369 in the IEEE OUI registry entry for B8:A4:4F. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Axis Communications AB own?

Axis Communications AB holds 4 OUI prefixes in the IEEE registry, of which B8:A4:4F is one. A device made by Axis Communications AB could carry a MAC address from any of them.
