Use standard public IP names

SYNOPSIS

Public IP address names should use a standard prefix.

DESCRIPTION

An effective naming convention allows operators to quickly identify resource type, associated workload, deployment environment and Azure region.

For public IPs, the Cloud Adoption Framework recommends using the pip- prefix.

Requirements for public IP names:

• At least 1 character, but no more than 80.
• Can include alphanumeric, underscore, hyphen, period characters.
• Can only start with a letter or number, and end with a letter, number or underscore.
• Public IP names must be unique within a resource group.

RECOMMENDATION

Consider creating public IPs with a standard name. Additionally consider using Azure Policy to only permit creation using a standard naming convention.

NOTES

This rule does not check if public IP names are unique.

To configure this rule:

• Override the CAF_PublicIPPrefix configuration value with an array of allowed prefixes.
• Override CAF_UseLowerNames with false to allow mixed case in resource names. By default only lower-case letters and other supported characters are allowed. This option affects all resource name rules.
