Which company owns MAC address prefix 24:62:AB?

MAC address prefix 24:62:AB is registered to Espressif Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:62:AB has a network interface built by Espressif Inc..

What is the OUI 24:62:AB?

24:62:AB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Espressif Inc.. It covers every address from 24:62:AB:00:00:00 to 24:62:AB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-62-AB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:62:AB:00:00:00 that is 24:62:AB — 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.
