This will loop from 1 to 254, perhaps not what you want. Alternatives:

$j = 1;
while ($j < 256) {
  ...
}

for my $j (1..256) {
}

Also consider Net-Ping.

Thanks for your ideas, but I really do want it to just do 1 through 254, but I do like the the `for my $j (1..256) { }` [download]	[reply] [d/l]

Just curious about the logic behind this correction.. Given that the network address (`.0`) and the broadcast address (`.255`) is rarely used for hosts (assuming last digit of a Class C network) then one would rarely want to ping the `.255` address.	[reply] [d/l] [select]

Well, I was going to say something about the evils of until/unless, but was really too tired to be coherent, so didn't end up saying all I meant. In other words, questioning the bounds was just an excuse to question the structure.	[reply]
