What is the OUI 98:7E:46?

98:7E:46 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Emizon Networks Limited. It covers every address from 98:7E:46:00:00:00 to 98:7E:46:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-7E-46.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:7E:46:00:00:00 that is 98:7E:46 — 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 Emizon Networks Limited located?

Emizon Networks Limited is listed at 1 Allerton Road Rugby Warwickshire GB CV23 0PA in the IEEE OUI registry entry for 98:7E:46. This is the address the organization registered with the IEEE, which may differ from its current operating address.
