That sounds like a bad idea, but go on.


: When I run this, I get an error "Can't localize lexical

: an error using "use strict".

Don't use local() in this circumstance.

sub ExcludeIPAddress {
my $ipAddress = shift;
my $subnet = shift;

return scalar grep /$ipAddress/,
@excludedIPAddresses,
$subnet->broadcast(),
$subnet->base();
}
