That is indeed correct, however
1. deregistering a DNS name does not cause arp caches to get flushed.
2. deregistering a DNS name at a server does not affect client caches where the name is still considered valid for the timeout that the DNS server previously reported.
3. arp caches can be added to and deleted manually and dynamic entries typically have a relatively short timeout.
