So far, nobody has noticed.</div><div><br></div><div>There's an alternative plan that would include re-implementing the functionality,</div><div>but there would have to be strong user case behind the work. But again, judging</div><div>from the fact that nobody has noticed, there doesn't seem to be strong user base</div><div>behind DSCP.</div><div><br></div><div>The deprecation will include:</div><div><br></div><div>* specifying the **dscp** option in following statements:</div><div> - `also-notify`</div><div> - `catalog-zones`</div><div> - `dual-stack-servers`</div><div> - `forwarders`</div><div> - `listen-on`</div><div> - `listen-on-v6`</div><div> - `notify-source`</div><div> - `notify-source-v6`</div><div> - `parental-source`</div><div> - `parental-source-v6`</div><div> - `query-source`</div><div> - `query-source-v6`</div><div> - `transfer-source`</div><div> - `transfer-source-v6`</div><div> - `parental-agents`</div><div> - `primaries`</div><div> - `</div><div>* following statements as whole:</div><div> - `dscp`</div><div><br></div><div><div>We plan to mark the options as deprecated in BIND 9.16 and 9.18 and remove it</div><div>in BIND 9.20 because it's already non-operational.</div></div><div><br></div><div>Cheers,</div><div>
