Status codes
- client delete prohibitedDeletion is locked at your registrar, so the domain cannot be accidentally (or maliciously) deleted.
- client transfer prohibitedTransfer lock is on — you must unlock this at your registrar before the domain can move to another one. This is usually a good thing: it is what stops someone else transferring your domain away.
- client update prohibitedUpdates are locked at your registrar — nameserver and contact changes will be refused until you remove the lock in your registrar account.
