Unless you need to keep the ordering of the values you should use a hash
like this.

my %data;

for (@list_of_ip) {
  $data{$_} = 1;
}

my @unique = keys %data;

I have a long list of IP addresses I am going to be reading in (using
regexps) and then seperating out into a list of IP addresses.  I don't
want the IP addresses to be printed if they are not unique.

Is there a way to check if a string already has an element in a stack?

i.e. push @stack, $_ if is_unique($_, @stack); ?

Or would I have to code that myself?
