CJSC NORSI-TRANS MAC Addresses

Primary OUI: 30:B3:46:
Total OUIs: 2
Last Updated: July 3, 2026

This page provides information about MAC addresses and OUIs assigned to CJSC NORSI-TRANS. The Organizationally Unique Identifier (OUI) is the first 24 bits of a MAC address and is assigned by the IEEE to uniquely identify a vendor or manufacturer.

About CJSC NORSI-TRANS MAC Addresses

MAC addresses beginning with 30:B3:46: are manufactured by CJSC NORSI-TRANS. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by CJSC NORSI-TRANS.

The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. CJSC NORSI-TRANS has been assigned the OUI prefix 30B346 (among others) for use in their network devices.

Common CJSC NORSI-TRANS Devices

Devices manufactured by CJSC NORSI-TRANS that you might encounter on networks include:

  • Network interface cards (NICs)
  • Routers and switches
  • Wireless access points
  • IoT devices
  • Embedded systems
  • And other networking equipment

Identifying CJSC NORSI-TRANS Devices on Your Network

To identify CJSC NORSI-TRANS devices on your network:

  1. Use network scanning tools to list devices on your network
  2. Look for MAC addresses starting with any of the OUI prefixes listed in the sidebar
  3. Use our MAC address lookup tool to confirm the manufacturer

This can be particularly helpful for network inventory, troubleshooting, and security auditing.

MAC Address Format

A complete MAC address consists of 48 bits (6 bytes) and is typically represented in hexadecimal format with each byte separated by a colon or a hyphen. For CJSC NORSI-TRANS devices, the MAC address would look like:

30:B3:46:XX:XX:XX

The first three bytes (30:B3:46) identify the manufacturer as CJSC NORSI-TRANS, while the last three bytes are unique to each device.
