Which company owns MAC address prefix 88:4A:18?

MAC address prefix 88:4A:18 is registered to Opulinks in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:4A:18 has a network interface built by Opulinks.

What is the OUI 88:4A:18?

88:4A:18 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Opulinks. It covers every address from 88:4A:18:00:00:00 to 88:4A:18:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-4A-18.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:4A:18:00:00:00 that is 88:4A:18 — 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 Opulinks located?

Opulinks is listed at F 28, No.328, Huashan Rd Shanghai CN 200040 in the IEEE OUI registry entry for 88:4A:18. This is the address the organization registered with the IEEE, which may differ from its current operating address.
