Made an amalgamation of two of the suggestions plus added a condition which is what I needed. Hope you find it useful. Basically my systems always have a left IP some have a peer system.

for (["Left",$system->{ip}->[0]], (["Right",$system->{peer}->[0]->{ip}
+->[0]])x!!(exists $system->{peer})) {
    my ($side, $ip) = @$_;
}
