Perform a DNS lookup to resolve the remote users' IP address to a hostname.
This is a Yes or No directive.
The default is No.
This directive is only available for use in the global
(interchange.cfg) configuration file,
and will affect all websites running under the Interchange installation.
It will not work in a website's local (catalog.cfg)
This directive specifies whether to perform DNS lookups to resolve remote
users' hostname from their IP address.
Hostnames are required for some facilities,
such as RobotHost.
Use RobotIP if you want to keep DNS lookups switched off.
If the web server is configured to perform hostname lookups itself
then this directive should remain disabled.
