Which company owns MAC address prefix 30:B8:9A?

MAC address prefix 30:B8:9A is registered to KRYON TECHNOLOGY PRIVATE LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:B8:9A has a network interface built by KRYON TECHNOLOGY PRIVATE LIMITED.

What is the OUI 30:B8:9A?

30:B8:9A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to KRYON TECHNOLOGY PRIVATE LIMITED. It covers every address from 30:B8:9A:00:00:00 to 30:B8:9A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-B8-9A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:B8:9A:00:00:00 that is 30:B8:9A — 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 KRYON TECHNOLOGY PRIVATE LIMITED located?

KRYON TECHNOLOGY PRIVATE LIMITED is listed at KRYON TECHNOLOGY PRIVATE LIMITED RBF 5 5G, DTZ, 380 Belerica Road, Sricity, Siddam Agraharam village, Varadaiahpalem, Tirupati, Andhra Pradesh, 517541 TIRUPATI ANDHRA PRADESH IN 517541 in the IEEE OUI registry entry for 30:B8:9A.
