srv lookup in record

[John Levine]

In article <mailman.838.1598399252.942.bind-users at lists.isc.org> you write:
>> [@temp3]$ dig +short srv _http-apps._server.test._tcp.marathon.mesos
>> 0 1 31024 server.test-usbzr-s3.marathon.mesos.
>> 0 1 31852 server.test-z9x84-s3.marathon.mesos.
>> 0 1 31790 server.test-k7g8r-s4.marathon.mesos.

These SRV records say that the service is on ports 31024, 31852, and 31790 on
the respective servers.  CNAME does not give you a port number.  There is no
way to fake SRV using CNAME.
