  • The /flushdns switch flushes the list of locally cached DNS names. When a name is resolved from DNS, the client keeps it in the cache temporarily. This option removes the cached entries.
  • The /registerdns switch allows the client to re-register its dynamic DNS entries as well as renew the DHCP lease.
  • The /displaydns switch lists the contents of your resolved DNS name cache.
