This one took me a moment. The split would have worked but for the
fact that the period character has special meaning to a regex. It
means "match any character". The split line should look like:
my(@octets) = split /\./, $dhcp{$hostname}->{ip};
Never use variables named $var1, $var2, etc. That is what arrays are for.
The reason the regex didn't work is that you never captured anything
(the parenthesis were in the wrong place):
my ($range) = $dhcp{$hostname}->{ip} =~ /(\d{1,3})$/;
