What is the OUI 74:CB:F3?

74:CB:F3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Lava international limited. It covers every address from 74:CB:F3:00:00:00 to 74:CB:F3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-CB-F3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:CB:F3:00:00:00 that is 74:CB:F3 — 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 Lava international limited located?

Lava international limited is listed at A-154D, Sector-63 Noida Uttar Pradesh IN 201301 in the IEEE OUI registry entry for 74:CB:F3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
