Which company owns MAC address prefix 00:1E:05?

MAC address prefix 00:1E:05 is registered to Xseed Technologies & Computing in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:1E:05 has a network interface built by Xseed Technologies & Computing.

What is the OUI 00:1E:05?

00:1E:05 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Xseed Technologies & Computing. It covers every address from 00:1E:05:00:00:00 to 00:1E:05:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-1E-05.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:1E:05:00:00:00 that is 00:1E:05 — 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 Xseed Technologies & Computing located?

Xseed Technologies & Computing is listed at Topaz House, MATAM Haifa IL 39100 in the IEEE OUI registry entry for 00:1E:05. This is the address the organization registered with the IEEE, which may differ from its current operating address.
