8.1. CoAP Content-Formats 注册表

IANA 已在 "Constrained RESTful Environments (CoRE) Parameters" 注册表组的 "CoAP Content-Formats" 注册表中, 为 "application/dns-message" 媒体类型分配了一个 CoAP Content-Format ID [RFC7252]; 这对应于 "Media Types" 注册表中的 "application/dns-message" 媒体类型 (见 [RFC8484]).

       +=========================+=====+===================+
       | 内容类型                | ID  | 参考文献          |
       +=========================+=====+===================+
