What this means
SRV records describe a service endpoint using priority, weight, port and target fields. They are often used by protocols that need service discovery, such as SIP or some messaging and directory services.
How to check it
Start with a live lookup for the domain or IP address involved. Compare the returned records with the configuration you expect, then confirm the related service is reachable. DNS and registration data can be cached or redacted, so verify important changes with the authoritative provider.
Common mistakes
Do not assume one result explains every symptom. Check the record type, hostname, TTL and the service behind the record. Keep DNS records, web-server settings and mail-provider settings aligned when you make a change.
