SRV Record Lookup Tool

Check SRV records instantly across global resolvers to validate your service discovery, ports, and load balancing rules.

How to troubleshoot service discovery with an SRV Lookup

Unlike standard records, SRV records require a very specific query format. To check an SRV record, you must include the service and protocol in your lookup (e.g., _sip._tcp.example.com). Enter your properly formatted service domain above to instantly query its active SRV records.

Interpreting your SRV results

  • Syntax Errors: If the lookup fails, double-check your formatting. The service and protocol MUST start with an underscore (_) and be separated by a dot.
  • Priority vs. Weight: The result will show several numbers. The lowest Priority is contacted first. If multiple records share the same priority, the Weight dictates how often that server should be chosen (higher weight = more traffic).
  • Target Resolution: The SRV record points to a target hostname (e.g., server1.example.com). This target MUST resolve to an A or AAAA record. If the target points to a CNAME, the SRV configuration is invalid according to DNS standards.
