This will increase the load on the authoritive DNS systems, but for a few days of transition ..... Most of the Australian DNS servers will/should be configured to have a forwarder entry to 139.130.4.4 anyway so a lower ttl (the default is normally 1 day or 86400 seconds) would cause uneeda.aarnet.edu.au to resolve more often.
