What is the OUI 38:98:D8?

38:98:D8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MERITECH CO.,LTD. It covers every address from 38:98:D8:00:00:00 to 38:98:D8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-98-D8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:98:D8:00:00:00 that is 38:98:D8 — 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.
