Parametric Search Appliance
This field defines the machine(s) and/or network(s) that constitute a
cluster of Parametric Search Appliances. You can specify multiple addresses with a
network prefix and wildcard (like 10.10.10.*),
netmask (like 10.10.1.0:255.255.255.0) , or address/prefixlen (like 10.10.1.0/24) format.
All machines matching these IPs will be allowed full access to the Parametric Search Appliance
internals without verification. This allows for replication and dataload.
If the request is forwarded such that a X-Forwarded-For header is
included (like a load balancer), all IPs through the forwarding chain must be
allowed by Cluster Members.
