Wide-area DNS Service Discovery for Apple devices
There are several ways you can add wide-area DNS Service Discovery (DNS-SD) to your network. One is to set up a dynamic DNS server to allow devices to automatically advertise their services. Another way is to manually add DNS records describing the services you want to advertise for other devices to discover. Conceptually, you can think of both these approaches as “read-only” DNS-SD. You don’t allow individual devices to dynamically register to advertise services, but you do allow all devices to query and discover a carefully selected set of services you’ve chosen to advertise, such as web pages.
Many organizations have internal websites for employees, staff, and students, often including a page of information for anyone new to the organization. Yet users may not know or remember the URL for the information page—and they may not remember that URL when they want to find the page later. Adding static service records to an organization’s authoritative DNS server offers a solution to this problem.
