Re^3: algorithm for network address enumeration

What does this do?

print(format_ipv4, $/)
   for ($first+1 .. $broadcast-1);

I would expect $_ there.

Edit: never mind. i get it:

print format_ip4($_);
print $/;

I wrote `format_ipv4` to use $_ if no arguments are supplied (like `length`, `split` and a number of other builtins do), so `print(format_ipv4, $/)` is the same as `print(format_ipv4($_), $/)`	[reply] [d/l] [select]
