What is the OUI E8:61:1F?

E8:61:1F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dawning Information Industry Co.,Ltd. It covers every address from E8:61:1F:00:00:00 to E8:61:1F:FF:FF:FF, or 16,777,216 addresses in total. It is also written E8-61-1F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:61:1F:00:00:00 that is E8:61:1F — 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 Dawning Information Industry Co.,Ltd located?

Dawning Information Industry Co.,Ltd is listed at NO.15 Huake Street,Hi-Tech Zone Tianjin CN 300384 in the IEEE OUI registry entry for E8:61:1F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
