What is the OUI E4:60:59?

E4:60:59 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Pingtek Co., Ltd.. It covers every address from E4:60:59:00:00:00 to E4:60:59:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-60-59.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:60:59:00:00:00 that is E4:60:59 — 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.
