Which company owns MAC address prefix 98:9F:1A?

MAC address prefix 98:9F:1A is registered to Private in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 98:9F:1A has a network interface built by Private.

What is the OUI 98:9F:1A?

98:9F:1A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Private. It covers every address from 98:9F:1A:00:00:00 to 98:9F:1A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-9F-1A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:9F:1A:00:00:00 that is 98:9F:1A — 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.
