What is the OUI 88:57:6D?

88:57:6D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to XTA Electronics Ltd. It covers every address from 88:57:6D:00:00:00 to 88:57:6D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-57-6D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:57:6D:00:00:00 that is 88:57:6D — 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 XTA Electronics Ltd located?

XTA Electronics Ltd is listed at The Design House Stourport-on-Severn Worcestershire GB DY13 9BZ in the IEEE OUI registry entry for 88:57:6D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
