.gov Registrar: Ensure unique and descriptive accessible names for IP Address form fields

[SamiyahKey]

Issue description

As a screen reader user, I need each “IP address (IPv4 or IPv6)” form field to have a unique and descriptive accessible name so that I can understand which server the field corresponds to and enter the correct IP address without confusion.

This will ensure compliance with Trusted Tester ID [1.3.1 Info and Relationships] and WCAG success criteria 2.4.4 Name, Role Value, which requires that the purpose fields be clear from their labels alone.

Current Issue:

• The IP address form fields currently share the same accessible name, making them indistinguishable for screen reader users.

• This creates confusion as users cannot determine which IP address field belongs to which server.

Acceptance criteria

• Each IP address form field has a unique and descriptive accessible name that clearly indicates the server it corresponds to (e.g., “Server 1 IP Address (IPv4 or IPv6),” “Server 2 – IP Address (IPv4 or IPv6)”).

• The accessible name should match or align with the visible label to provide a consistent experience.

• Screen readers should announce distinct labels for each IP address field.

• Implementation should be verified using assistive technologies such as NVDA, JAWS, or VoiceOver.
