This pull request enhances the audit routing data source management to support domain names in addition to IP addresses. The change updates the JDBC URL parsing logic to accept hostnames (including localhost and fully qualified domain names) while maintaining backward compatibility with existing IP-based configurations.

Changes:

• Updated regex pattern in RouteUtils.extractAddress() to accept domain names, not just IP addresses
• Added error handling and logging for JDBC URL parsing failures
• Introduced comprehensive test coverage for domain name scenarios including localhost, single-level, multi-level, and hyphenated domains
