That's why I changed them pointing to tjener.intern, the machine where
the service is actually running after the default installation.
To move services to other machines, these pointers have to be changed
accordingly. (With multiple A-records in place, you have to modify the
A-records and PTR-records to correspond to the new machine. In that
case you can leave the SRV-records untouched. Now you have to add the
PTR- and A-record to the new machine, remove the CNAME and modify the
SRV-record to point to that new machine.)
Is there a problem with that I've missed?
