Which company owns MAC address prefix 10:19:88?

MAC address prefix 10:19:88 is registered to Mother Computer Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:19:88 has a network interface built by Mother Computer Inc..

What is the OUI 10:19:88?

10:19:88 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Mother Computer Inc.. It covers every address from 10:19:88:00:00:00 to 10:19:88:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-19-88.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:19:88:00:00:00 that is 10:19:88 — 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 Mother Computer Inc. located?

Mother Computer Inc. is listed at 103 Pioneer Way, Ste B Mountain View CA US 94041 in the IEEE OUI registry entry for 10:19:88. This is the address the organization registered with the IEEE, which may differ from its current operating address.
