Which company owns MAC address prefix EC:E7:8E?

MAC address prefix EC:E7:8E is registered to AsiaTelco Technologies Co. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:E7:8E has a network interface built by AsiaTelco Technologies Co..

What is the OUI EC:E7:8E?

EC:E7:8E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AsiaTelco Technologies Co.. It covers every address from EC:E7:8E:00:00:00 to EC:E7:8E:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-E7-8E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:E7:8E:00:00:00 that is EC:E7:8E — 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 AsiaTelco Technologies Co. located?

AsiaTelco Technologies Co. is listed at No. 68 Huatuo Road, Building-8,Zhangjiang Hi-Tech Park, Pudong Shanghai Shanghai CN 201203 in the IEEE OUI registry entry for EC:E7:8E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
