Configuring a DNS Server
To configure a DNS server using GNS:
1 Configure GNS VIP address on DNS server—In the DNS, create a name
resolution entry for the GNS virtual IP address in the forward Lookup zones.
a Open the DNS manager .
b Click DNS server  Forward Lookup Zones  DNS Domain .
c Right-click DNS domain and select New Host (A or AAAA) .
d In the New Host windows, enter the name and IP address for GNS
virtual IP address.
e Click Add Host .
f Click OK.
g Click Done on New Host window.
For example:
gns-server Host A 192.0.2.2
Where, gns-server is the GNS virtual IP address given during grid
installation. The address that you provide must be routable and
should be in public range. For example, 192.0.2.2.
2 Configure the GNS sub-domain delegation—In the DNS server, establish
DNS Lookup that directs the DNS resolution of a GNS sub-domain to the
cluster. Open the DNS-Manager and do the following:
a Click DNS server  Conditional Forwarders .
b Right-click Conditional Forwarders and select New Conditional
Forwarder.
c In the New Conditional Forwarders window, enter the GNS sub-
domain and GNS VIP address (which you must provide during grid
installation).
Example:
clusterdomain.subdomain.com (GNS Sub-
domain) 192.0.2.2
(GNS VIP configured in the step 1)
d Click OK.
e Restart the DNS service.
