I have a script that does ping on my Solaris 7 OS but I need it to email me if an IP address does not ping.

I tried to use the Unix exit status to find invalid ip addresses ($? = EXIT STATUS...IF 0 THEN IT SUCCEEDED, IF OTHER THEN FAILED) then I would be able to email myself if an IP address didnt ping. My exit status check is not working. Anyone have a better idea of how I could do this?? 
#!/usr/local/bin/perl
@a = (<DATA>);
$s = system("$?");
foreach (@a)
{
system("/usr/sbin/ping $_");
print system("$?\n");
if ( $? != 0)
{
        print "Could not ping host.";
}
else
{
        print "Ping successful.\n";
}
}
close(DATA);
