U2S co. MAC Addresses
This page provides information about MAC addresses and OUIs assigned to U2S co.. 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 U2S co. MAC Addresses
MAC addresses beginning with C4:E1:7C: are manufactured by U2S co.. When you see a device on your network with this OUI prefix, it indicates that the device was manufactured by U2S co..
The IEEE assigns OUI prefixes to manufacturers to ensure uniqueness in the global networking ecosystem. U2S co. has been assigned the OUI prefix C4E17C (among others) for use in their network devices.
Common U2S co. Devices
Devices manufactured by U2S co. 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 U2S co. Devices on Your Network
To identify U2S co. devices on your network:
- Use network scanning tools to list devices on your network
- Look for MAC addresses starting with any of the OUI prefixes listed in the sidebar
- 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 U2S co. devices, the MAC address would look like:
C4:E1:7C:XX:XX:XX
The first three bytes (C4:E1:7C) identify the manufacturer as U2S co., while the last three bytes are unique to each device.
