Dynamic dns-based service discovery

Techniques are provided for performing dynamic DNS-SD. In an embodiment, an apparatus includes one or more databases, one or more transceivers to receive a first Domain Name System (DNS) query from a first computing device, the first DNS query defining a first service discovery name space, and one or more processors in communication with each of the one or more databases and the one or more transceivers. The one or more processors generate and append a first metadata associated with the first computing device to the first DNS query. The one or more transceivers transmit the first DNS query and the first metadata to a Domain Name System (DNS) server computer, receive, from the DNS server computer, a first response responsive to the first DNS query, and relay, to the first computing device, the first response. 用于执行动态DNS-SD的技术被提供。在实施例中，装置包括：个或多个数据库；个或多个收发器，用于从第计算设备接收第域名系统(DNS)查询，第DNS查询定义第服务发现名称空间；以及个或多个处理器，与个或多个数据库和个或多个收发器中的每项进行通信。个或多个处理器生成与第计算设备相关联的第元数据并将其附加于第DNS查询。个或多个收发器将第DNS查询和第元数据发送到域名系统(DNS)服务器计算机，从DNS服务器计
