A zone transfer allows another DNS server to download the complete list of
hosts maintained by your DNS server. By default, zone transfers are
unrestricted. However, you can restrict zone transfers if you want.
Enter IP addresses or network addresses in the Zone Transfer Access field;
this automatically causes zone transfers to become restricted. Now, only the
IP addresses or network addresses listed in this field are able to perform zone
transfers.
