+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:
