Look up DNS SRV records to discover service endpoints. Used by SIP, XMPP, Matrix, Minecraft, Kubernetes and more.

SRV (Service) records are a DNS record type that lets administrators publish the hostname and port for a service running on a domain. Applications query them automatically, without needing hard-coded server addresses.
The name format is _service._protocol.domain. For example, a SIP client queries _sip._tcp.example.com to find all SIP servers, their ports, and priority order. Lower priority numbers are contacted first. Weight distributes load among servers sharing the same priority.
Common uses include SIP and VoIP telephony, XMPP chat servers, Matrix federated messaging, Minecraft server discovery, and Kubernetes API endpoints. If a service supports SRV lookup, server addresses can change without touching any client configuration.
