Resolution line enumeration

Resolution line priority rules

When multiple records with different resolution request sources are configured for the same domain name, the following rules apply:

• Cross-category priority: Custom lines > Search engine lines > Cloud provider lines > ISP lines > Region lines > Default line

• Within the same category: more specific lines take higher priority
