Ubuntu changed the name of the network interface how is that possible?

Question

ubuntu

Ubuntu 18.04.5 LTS (GNU/Linux 5.4.0-62-generic x86_64)

Server changes network interface name sometimes!
As a result, everything falls down to changing it in the config

. Something I heard in my opinion once at 18 once at that time there was a transition to yaml
but not a fact

Answer 1

The primary device naming scheme has changed. Priorities:
1. eno1 - network device 1 on the motherboard. It is used if it is possible to obtain information about integrated devices from the BIOS.
2. ens4 - network device in the PCI express hot-plug slot 4. Used if it is possible to get information about devices on the PCIe bus from the BIOS.
3. enp4s0 - network device 0 in PCI slot 4. Used if it is possible to determine the slot.
4. eth0 - network device 0. Used if the previous schemes do not fit. The device order is determined by the driver loading order.
5. enx78e7d1ea46da - network device with MAC address 78:e7:d1:ea:46:da. This mode can be enabled manually.
