Remote_Host Code - Get Host Name from Users IP

[qwik]

What is the code to retrieve the Remote_Host from a user?

I tried $REMOTE_HOST and it does not display anything.

Is there a different command that I could use to retrieve the Hostname from a user?

I saw this command <urlcp dnsmode sys> - but I still can not get it working to display the Hostname of the user.

Thanks.

$REMOTE_HOST is often not set these days because webservers are configured not to lookup client IPs for speed.

You can use <nslookup $REMOTE_ADDR> to get the name for
the client's IP.
