org.xbill.DNS.Record

org.xbill.DNS.SRVRecord

All Implemented Interfaces:

Serializable, Cloneable, Comparable<Record>

public class SRVRecord
extends Record

Server Selection Record - finds hosts running services in a domain. An SRV record will normally be named _<service>._<protocol>.domain - examples would be _sips._tcp.example.org (for the secure SIP protocol) and _http._tcp.example.com (if HTTP used SRV records)

getAdditionalName

public Name getAdditionalName()

Description copied from class: Record

Returns the name for which additional data processing should be done for this record. This can be used both for building responses and parsing responses.

Overrides:

getAdditionalName in class Record

Returns:

The name to used for additional data processing, or null if this record type does not require additional data processing.
