Re: Adding an Entire Class B IP Range to an Array

You can use map from within map which would be quite ugly for more than 2 levels an quite hard for n levels where n is determined at runtime.

my @hosts = map {my $i = $_; map {"192.168.$i.$_"} 1 .. 254} 1 .. 254;

[nesting maps] would be quite hard for n levels where n is determined at runtime That's what Algorithm::Loops 'NestedLoops' is for. And (because I need to practice using it) the solution corresponding to yours would be `use Algorithm::Loops 'NestedLoops'; my @hosts = NestedLoops([([1..254])x2], sub { "192.168.$_[0].$_[1]" }) +;` [download] Caution: Contents may have been coded under pressure.

The outer 1..254 (3rd octet) should be 0..255 if you don't wanna skip 510 valid addresses.	[reply]
