'''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. 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>.

The convention was implemented for [[Dell]] in a module called <code>{{Mono|biosdevname</code>}}.<ref name="digit">{{Cite web |title= Fedora 15 Changing The Network Device Naming Scheme |work= Digitizer Linux News |url= http://digitizor.com/2011/01/25/fedora-15-network-device-naming/ |date= January 25, 2011 |accessdate= May 27, 2013 }}</ref>
