Which company owns MAC address prefix E0:91:53?

MAC address prefix E0:91:53 is registered to XAVi Technologies Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:91:53 has a network interface built by XAVi Technologies Corp..

What is the OUI E0:91:53?

E0:91:53 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to XAVi Technologies Corp.. It covers every address from E0:91:53:00:00:00 to E0:91:53:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-91-53.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:91:53:00:00:00 that is E0:91:53 — 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 XAVi Technologies Corp. located?

XAVi Technologies Corp. is listed at 9F., No129, Xingde RD.,Sanchong Dist., New Taipei Taiwan TW 24158 in the IEEE OUI registry entry for E0:91:53. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does XAVi Technologies Corp. own?

XAVi Technologies Corp. holds 2 OUI prefixes in the IEEE registry, of which E0:91:53 is one. A device made by XAVi Technologies Corp. could carry a MAC address from any of them.
