enp3s0
enp3s0 is a modern Linux network interface name assigned to a specific Ethernet device using the predictable network interface naming scheme implemented by udev/systemd. This naming approach replaces older names like eth0 and is designed to reflect the hardware location of the device on the PCI Express bus, providing persistent identification across reboots and re-enumerations.
The name enp3s0 encodes the PCI location as follows: enp indicates an Ethernet device on the PCI
This naming is assigned at boot time by the system’s udev rules and can vary between systems
To identify or manage enp3s0, administrators commonly use commands such as ip link show enp3s0, ethtool enp3s0,
