dns_aliases.cfg is used to configure global collection access restriction per hostname. This file specifies which collection names are valid for specific hostnames. It allows you to restrict access to collections based on the hostname requested by the search user. This configuration file is only relevant if your Funnelback instance serves multiple hostnames.

If the collection requested is not valid for the hostname, the search user will be redirected to the first valid collection for this hostname.

This configuration can only be modified by a system administrator.
