Presence Services clients in each data center must be able to resolve the FQDN of the Presence Services cluster HTTP load balancer called the Service FQDN. The Service FQDN must resolve to the IP address that is configured as the Cluster IP in System Manager. Cluster IP is configured by using the System Manager.
Configure the cluster IP address.

ADDITIONAL INFORMATION:
Note:
The cluster fully qualified domain name or Cluster FQDN must be left empty for Geographic Redundancy configuration. It can be provisioned for other types of deployments. The Cluster Fully Qualified Domain Name attribute is available in the Basic section below the Cluster IP in System Manager.
The two data center DNS servers must be configured differently from each other to ensure that clients in each data center connect to the local Presence Services cluster, even if they are provisioned to access the Presence Server cluster in the geographically remote data center. Ensure that the two data center DNS servers are configured as follows:
Data center 1 must have both the clusters Presence Services service FQDN’s, such as the local cluster and the geographic remote cluster Service FQDNs resolving to the local Presence Services cluster IP address.
Similarly, data center 2 must have both the clusters Presence Services service FQDNs resolving to its local Presence Services cluster IP address.
