Which company owns MAC address prefix 98:CA:20?

MAC address prefix 98:CA:20 is registered to Shanghai SIMCOM Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 98:CA:20 has a network interface built by Shanghai SIMCOM Ltd..

What is the OUI 98:CA:20?

98:CA:20 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai SIMCOM Ltd.. It covers every address from 98:CA:20:00:00:00 to 98:CA:20:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-CA-20.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:CA:20:00:00:00 that is 98:CA:20 — 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 Shanghai SIMCOM Ltd. located?

Shanghai SIMCOM Ltd. is listed at Building A, SIM Technology Building, No.633, Jinzhong Road, Changning District Shanghai CN 200335 in the IEEE OUI registry entry for 98:CA:20. This is the address the organization registered with the IEEE, which may differ from its current operating address.
