-In the case of Jamulus, the `service` must be `jamulus` and the `proto` must be `udp`, so the record will look like this:
+Note that the `name` and `target` hostnames may either be the same or different. `name` is the hostname the user will use without a port number for SRV lookup, and `target` is the hostname the Jamulus will use together with the discovered port number in order to connect to the Jamulus Server or Directory.

-This allows to host many Jamulus Servers or Directories at different ports on a single host with different hostnames by giving each its own SRV record. This avoids having to give your users the port number, which may be less memorable than a name.

In the above example, the user will specify `myserver.example.com` and Jamulus will then connect to `myhost.example.com:12345`.
