'''Consistent Network Device Naming''' is a convention for naming [[Ethernet adapter]]s in [[Linux]].

It was created around 2009 to replace the old {{Mono|ethX}} naming scheme that caused problems on [[Multihoming|multihomed]] machines because the [[network interface controller]]s (NICs) would be named based on the order in which they were found by the kernel as it booted. Removing existing or adding new interfaces could cause the previously added ones to change names.<ref>{{Cite web |title= Network Device Naming mechanism and policy |date= October 9, 2009 |author= Matt Domsch |work= LWN |publisher= Eklektix, Inc |url= https://lwn.net/Articles/356900/ |accessdate= May 27, 2013 }}</ref> An ECR was submitted to the PCI SIG firmware group on how system firmware can provide device naming to operating systems via the ACPI interface.<ref>{{Cite web |url=https://pcisig.com/sites/default/files/specification_documents/ECR_Slot_Naming-10.pdf |title=Archived copy |access-date=2017-02-22 |archive-url=https://web.archive.org/web/20170106042937/https://pcisig.com/sites/default/files/specification_documents/ECR_Slot_Naming-10.pdf |archive-date=2017-01-06 |url-status=dead }}</ref>
