Click Add to add or Remove to remove the entries. Choose one of the following from the TYPE drop-down list:
   
   • Any Address/Network: Choose this option to allow or deny queries from any IP addresses or networks. The PERMISSION column displays Allow by default. In that case, the application replies to queries from all clients. You can change it to Deny by clicking the field and choosing Deny from the drop-down list.

   • IPv4 Address: Choose this option to add an IPv4 address. Click the VALUE field and enter the IP address of the remote server. The PERMISSION column displays Allow by default. You can change it to Deny by clicking the field and choosing Deny from the drop-down list.

10. An rdatatype (short for resource record type) refers to the specific type of resource record (RR) in the DNS. Each resource record in DNS has an associated type that indicates the kind of data it holds for example type A, the IPv4 address of a NIOS-X Server, or type MX , how to route mail. An rdataset refers to a set of resource records (RRs) of the same type for a specific domain name in the Domain Name System (DNS). An rdatatype (short for resource record type) refers to the specific type of resource record (RR) in the DNS. Each resource record in DNS has an associated type that indicates the kind of data it holds for example type A, the IPv4 address of a NIOS-X Server, or type MX , how to route mail. An rdataset refers to a set of resource records (RRs) of the same type for a specific domain name in the Domain Name System (DNS). Excessively large rdatasets or large numbers of rrtypes can slow down query processing, therefore limits can be set on a per-zone basis. The value, “0”, removes any upper limit. However, this may result in reduced performance. Configure the following settings:
    • Max Records per Type: Specify a numeric value for maximum records per type. The default value is 2000.
    • Max Types per Name: Specify a numeric value for maximum types per name. The default value is 100.

11. Click Save & Close to save.

    After a primary zone is created, you can add resource records to it. For more information, see Configuring Resource Records.
