 +A Service Record (SRV record) is a specification of data in the [Domain Name System](/​glossary/​d/​dns) containing information about [IP](/​glossary/​i/​ip) and [port](/​glossary/​p/​port) for a specific service.
 +
 +It is used by domain servers to keep track of their own changes without having to contact a central DNS server.
