What is the OUI 44:EA:54?

44:EA:54 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to UDISENSE DBA NANIT. It covers every address from 44:EA:54:00:00:00 to 44:EA:54:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-EA-54.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:EA:54:00:00:00 that is 44:EA:54 — 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 UDISENSE DBA NANIT located?

UDISENSE DBA NANIT is listed at 244 5th Ave #2702 NEW YORK NY US 10001 in the IEEE OUI registry entry for 44:EA:54. This is the address the organization registered with the IEEE, which may differ from its current operating address.
