Questions about the SRV lookup
What is an SRV record?
A record that tells clients which host and port run a service, such as SIP calls or Microsoft Autodiscover.
How do I write the service name?
Start with the service and protocol labels, then the domain: _service._protocol.yourbrand.com, for example _autodiscover._tcp.yourbrand.com.
What do priority and weight mean?
Clients try the lowest priority first. Among servers with the same priority, weight sets how the load is shared.
