Add a name server

You can create a name server by specifying its IP address or by configuring an existing virtual server as the name server.

While adding name server, you can provide an IP address or a virtual server IP address. If you add IP address based name servers, the Citrix ADC appliance load balances requests to the configured name servers in round robin method. If you add a virtual server, you can configure any load balancing method.

To verify the configuration, you can use the sh dns <recordtype> <domain> command. If the queried records are not present in the cache, the resource records are fetched from the configured external name servers.

Add a name server (when the Citrix ADC appliance acts as a forwarder) by using the CLI

At the command prompt, type;

add dns nameServer ((<IP>) | <dnsVserverName>)

or

add dns nameServer ((<IP> | <dnsVserverName>) [-type <type>]

Example:

add dns nameServer 192.0.2.10  

add dns nameServer dnsVirtualNS

add dns nameServer 192.0.2.11  -type TCP

add dns nameServer 192.0.2.12  -type UDP_TCP

Note:

If the name server type is not specified, a UDP name server is created by default. To create a name server of type TCP or UDP_TCP, you must specify the type.

When you specify the type as UDP_TCP, two name servers (one UDP name server and one TCP name server) are created for the given IP address.

Add a name server (when the Citrix ADC appliance acts as a resolver) by using the CLI

At the command prompt, type:

add dns nameServer ((<IP> [-local]) | <dnsVserverName>)

Example:

add dns nameServer 10.102.9.19 -local

Note:

• To remove a name server, at the Citrix ADC CLI, type the rm dns nameServer command followed by the IP address of the name server.
• To view the details of the DNS nameserver, at the Citrix ADC CLI, type show dns nameServer command followed by the IP address of the name server.

Add a name server by using the GUI

Navigate to Traffic Management > DNS > Name Servers and create a name server.
