A test case the skill fixed. Same model, same prompt, with and without the skill.
When private DNS queries fail to resolve an internal record, we want to control whether the query falls back to public internet resolution versus immediately returning NXDOMAIN. Which Azure Private DNS configuration setting controls internet fallback behavior?
