Hey monks,

Net::Pcap provides a function lookupnet to query a host's network interface and to return its network and and netmask setting.

However, when running 

use Net::Pcap;

my $err;
my($address, $netmask);
my $dev = Net::Pcap::lookupdev(\$err);
print "dev is $dev\n";

if(Net::Pcap::lookupnet($dev, \$address, \$netmask, \$err)) {
    die "Failed to look up dev info on $dev";
}

print "address=$address netmask=$netmask\n";

[download]
the output is something like 
dev is eth0
address=-1062731776 netmask=-256

Which format is this in? I've tried inet_ntoa and friends but can't seem to convert the result to the xx.xx.xx.xx format I'm looking for. Any ideas?
