Source notes citing this source

• RFC 2782 obsoletes RFC 2052. in context
• An SRV record's owner name has the form _Service._Proto.Name, and the record carries priority, weight, port and target fields. in context
• Under RFC 2782 a client must attempt the reachable target with the lowest-numbered priority first. in context
• Under RFC 2782 an SRV target of '.' means the service is decidedly not available at that domain. in context
• Under RFC 2782 the SRV target must not be an alias (a CNAME). in context
• Under RFC 2782, among records of equal priority, larger weights should be given a proportionately higher probability of selection, and weight-0 records get a very small chance of selection when others exist. in context
