Some places say I should others so no.
Also when ever I use the variable $ENV{'REMOTE_HOST'} in perl it gives nothing.

I definitely recommend you setup reverse DNS. As far as your problem with perl, I never herd of that problem. Maybe you have an error in your code?

Ok, thanks for the reverse DNS help. As for my code, it is the same code I used on my old server. It also works on my local machine.

$ENV{'REMOTE_HOST'} is not supported on all servers. This may be why.

I thought Perl on every machine supported this. Does it have to do with the Perl version or do some server os'es unplug that comman?

REMOTE_HOST is environment variable defined by CGI version 1.1. It has nothing to do with Perl. Is there is no environment variable called REMOTE_HOST, $ENV{'REMOTE_HOST'} produces no result.

I see. Thanks for clarifying this.

You have to turn on your HostNameLookup in your Apache config (I don't know other webservers) to get the REMOTE_HOST. Without it the IP of the client is stored in REMOTE_ADDR.

Thanks, I just figured it out yesterday.
