FAQ
- Which company owns MAC address prefix 20:36:D7?
- MAC address prefix 20:36:D7 is registered to Shanghai Reacheng Communication Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:36:D7 has a network interface built by Shanghai Reacheng Communication Technology Co.,Ltd.
- What is the OUI 20:36:D7?
- 20:36:D7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai Reacheng Communication Technology Co.,Ltd. It covers every address from 20:36:D7:00:00:00 to 20:36:D7:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-36-D7.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 20:36:D7:00:00:00 that is 20:36:D7 — 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.
