Ip address with the address 192.168.0.0 network in http request header

Using mod_perl for Apache 1.3. Address of the client get the headers X-Forwarded-For, HTTP_X_FORWARDED_FO,or environment variable $ENV{REMOTE_ADDR}:

sub address {
    my $self = shift;
    unless(defined $self->{address}){
        my $header = $self->apache->headers_in->{'X-Forwarded-For'} ||
            $ENV{HTTP_X_FORWARDED_FOR} || '';
        my ($ip) = $header =~ /([^,\s]+)$/;
        $self->{address} = $ip || $ENV{REMOTE_ADDR} || ''; 
    }
    return $self->{address};
}

The problem is that sometimes there are addresses such as 192.168.200.11, 192.168.1.156, 192.168.0.73. Although the server is not connected to the network 192.168.0.0.

Expected as you are explicitly looking at HTTP_X_FORWARDED_FOR header that (if properly set by all proxies on a way) will contain all intermediate IP and original client IP. Since most people are in local home networks most originating IPs are in 192.168.xx.xx range.
