FAQ
- Which company owns MAC address prefix D8:AE:D0?
- MAC address prefix D8:AE:D0 is registered to Shanghai Engineering Science & Technology Co.,LTD CGNPC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:AE:D0 has a network interface built by Shanghai Engineering Science & Technology Co.,LTD CGNPC.
- What is the OUI D8:AE:D0?
- D8:AE:D0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai Engineering Science & Technology Co.,LTD CGNPC. It covers every address from D8:AE:D0:00:00:00 to D8:AE:D0:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-AE-D0.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in D8:AE:D0:00:00:00 that is D8:AE:D0 — 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.
- Where is Shanghai Engineering Science & Technology Co.,LTD CGNPC located?
- Shanghai Engineering Science & Technology Co.,LTD CGNPC is listed at No.1588, Rd Zixing Shanghai Shanghai CN 200241 in the IEEE OUI registry entry for D8:AE:D0. This is the address the organization registered with the IEEE, which may differ from its current operating address.
