If you want to renumber several hosts (e.g. moving hosts en masse between subnets), please submit a request to hostmaster; do not make any assumptions about the resulting addresses assigned by the system. Moving hosts between zones can only be done by users with hostmaster privileges, though less privileged users can renumber a host within a zone or delete an existing host and re-create it in the appropriate zone.

If you are hostmaster and want to move several hosts from one IP range to another, use Batch Host Move from the Admin screen. The option to attempt to retain the last octet should be enabled for most moves.
