OD: Originating domain (where the controllable DNS "tree" starts)
Public OD: redxen.eu
Local OD: redxen.localhost
Machine format (<mformat>): <unique-id>.<datacenter-identifier>.<provider>
Familiar format (<fformat>): <familiar-name>.<location>.<provider>
SRV records:
<service>.routinginfo.OD
( <mformat> / <fformat> ).routinginfo.OD
<service>.( <mformat> / <fformat> ).routinginfo.OD
Machine identifier: <mformat>.OD
Familar identifier: <fformat>.OD
SRV records are based on a per-service or/and per-host base.
rDNS: points to familiar identifier
Familiar names are going to be canonical names to machine formats and the machine formats SHOULD have no overlapping.
The familiar format <location>.OD may contain all the records for the children of that tree.
Examples for records:
