SRV record
Advertises the host and port for a specific service, letting clients discover where a protocol lives without hard-coded settings.
What one looks like
_sip._tcp.example.com. 3600 IN SRV 10 60 5060 sipserver.example.com.
Things worth knowing
- Used by SIP, XMPP, Minecraft servers and Microsoft 365 autodiscover.
- The fields are priority, weight, port and target — in that order.
- The name must include the service and protocol prefixes with underscores.
