Subnet names should meet naming requirements.

Description#

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

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

Recommendation#

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

Notes#

This rule does not check if subnet names are unique.
