The replies here are over-simplified. First,  $ENV{REMOTE_ADDR}

isn't always defined, depending on VPN, proxies, etc.

Second, you were seeking an IP- $ENV{REMOTE_HOST} is a name, which can presumably resolve to an IP, but the same network restrictions may apply for both.

Last, 

my $q = new CGI;
my $userIP = $q->remote_addr();

probably uses %ENV as well, so the IP may or may not be defined.

in the simple-case, you MAY be able to get the IP. In a secure corporate case like ours, it dubious. I suspect the replies that stated use  $ENV{REMOTE_ADDR} only use this on simple networks. In my world and perhaps yours, things just aren't that easy;I wish they we're since this *simple* IP is in-fact a major PAIN for us.
