config global-dns-server zone
Use this command to configure DNS zone and resource records.
The DNS zone configuration is the key to the global load balancing solution. This configuration contains the key DNS server settings, including:
- Domain name and name server details.
- Type—Whether the server is the master or a forwarder.
- DNSSEC—Whether to use DNSSEC.
- DNS RR records—The zone configuration contains resource records (RR) used to resolve DNS queries delegated to the domain by the parent zone.
You can specify different DNS server settings for each zone you create. For example, the DNS server can be a master for one zone and a forwarder for another zone.
Before you begin:
- You must have a good understanding of DNS and knowledge of the DNS deployment in your network.
- You must have authority to create authoritative DNS zone records for your network.
- You must have read-write permission for global load balancing settings.
After you have configured a DNS zone, you can select it in the DNS policy configuration.

config global-dns-server zone |
|
type |
|
domain-name |
The domain name must end with a period. For example: |
negative-ttl |
The last field in the SOA—the negative caching TTL. This informs other servers how long to cache no-such-domain (NXDOMAIN) responses from you. The default is 3600 seconds. The valid range is 0 to 2,147,483,647. |
primary-server-ip |
IP address of the primary server. |
primary-server-ip6 |
IP address of the primary server. |
primary-server-name |
Sets the server name in the SOA record. |
responsible-mail |
Username of the person responsible for this zone, such as |
ttl |
The $TTL directive at the top of the zone file (before the SOA) gives a default TTL for every RR without a specific TTL set. The default is 86,400. The valid range is 1 to 2,147,483,647. |
forward |
|
forwarders |
Specify a remote server configuration object. |
dnssec-status |
Enable/disable DNSSEC. |
dnssec-algorithm |
RSHSHA1 is the only supported algorithm. |
dsset-info |
It is generated by the system if DNSSEC is enabled for the zone. |
dssetinfo-filename |
The file is generated by the system if DNSSEC is enabled for the zone. The file generated by the zone configuration editor is the one you give to any parent zone or the registrar of your domain. The convention is dsset-<domain>, for example |
dsset-info-list |
Specify a DSset info list configuration object. |
KSK |
Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone. |
KSK-Filename |
The file is generated by the system if DNSSEC is enabled for the zone. To regenerate the KSK, disable DNSSEC and then re-enable DNSSEC. |
ZSK |
Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone. |
ZSK-Filename |
The file is generated by the system if DNSSEC is enabled for the zone. To regenerate the ZSK, disable DNSSEC and then re-enable DNSSEC. |
config a-aaaa-record |
|
hostname |
The hostname part of the FQDN, such as Note:
|
source-type |
IPv4 or IPv6 |
ip |
IP address of the virtual server. |
ip6 |
IP address of the virtual server. |
method |
Weighted Round Robin is the only method supported. |
weight |
Assigns relative preference among members—higher values are more preferred and are assigned connections more frequently. The default is 1. The valid range is 1-255. |
config cname-record |
|
alias |
An alias name to another true or canonical domain name (the target). For instance, |
target |
The true or canonical domain name. For instance, |
config mx-record |
|
hostname |
The hostname part of the FQDN for a mail exchange server, such as |
type |
IPv4 or IPv6 |
ip |
IP address of the mail server. |
ip6 |
IP address of the mail server. |
priority |
Preference given to this RR among others at the same owner. Lower values have greater priority. |
config ns-record |
|
domain-name |
The domain for which the name server has authoritative answers, such as |
host-name |
The hostname part of the FQDN, such as |
type |
IPv4 or IPv6 |
ip |
IP address of the name server. |
ip6 |
IP address of the name server. |
config txt-record | |
name |
Hostname. TXT records are name-value pairs that contain human readable information about a host. The most common use for TXT records is to store SPF records. |
text |
Comma-separated list of name=value pairs. An example SPF record has the following form: "v=spf1 +mx a:colo.example.com/28 -all"
If you complete the entry from the CLI, put the string in quotes. (If you complete the entry from the the Web UI, you do not put the string in quotes.) |
config srv-record | |
hostname |
The SRV Hostname. |
target-server |
The target server name (record). |
config ptr-record | |
PTR Address |
A PTR address, such as 10.168.192.in-addr.arpa. or 1. If you use the number, the domain name is in the format "x.x.x.in-addr.arpa.". |
FQDN |
A fully qualified domain name, such as "www.example.com". |
