(And which logs to a different fileset!) Hrm. Laboring a point, the zones maintained by APNIC have the incorrect MNAME field, as the zones are generated on a machine within RFC1918 space and then exported out on a weekday basis. Changing this field to a different host (or a different IP on ns.apnic.net) presents no operational hazard for the zones that we host.

As of next reload (~5 minutes), the MNAME field (and only the MNAME, not the serial) of our zones will refer to a different host. This will be left in place for a week to see what appears in the logs of that host. FYI, the current rate that we are seeing on ns.apnic.net is roughly 1.5 'unauthorised updates' per second, peaking at 6/s over the last week.
