How I can break out my foreach loop?

I'm checking if IP exists on a Cisco routing table, if it does then we can get more info. I want to say if the IP doesn't exist then break the loop with error. I have the following and it works great until I enter a non-valid IP which doesn't exist on my router:

    foreach $match ( @Output ) {
        if ( $match =~ m/^Routing entry for / ) {
            @Data = split( ' ', $match );
            $octet = $Data[ 3 ] ;
            last ;
        }
    }
    my @routing = split( /\./, $octet );

How I can add to say if m/^Routing entry for / didn't show up in all lines then die()? I have tried many ways and it never works
