Use valid subnet names#
Operational Excellence · Virtual Network · 2020_06
Subnet names should meet naming requirements.
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.
Consider using names that meet subnet naming requirements. Additionally consider naming resources with a standard naming convention.
This rule does not check if subnet names are unique.
