Use valid NIC names#

Operational Excellence · Virtual Machine · 2020_06

Network Interface (NIC) names should meet naming requirements.


When naming Azure resources, resource names must meet service requirements. The requirements for Network Interface names are:

  • Between 1 and 80 characters long.
  • Alphanumerics, underscores, periods, and hyphens.
  • Start with alphanumeric.
  • End alphanumeric or underscore.
  • NIC names must be unique within a resource group.


Consider using names that meet Network Interface naming requirements. Additionally consider naming resources with a standard naming convention.


This rule does not check if Network Interface names are unique.
