我已经成功安装了NetAddr通过这个：cpan -i NetAddr::DNS
现在我试着启动这个基本程序：

use Net::IP;

my $ip = new Net::IP ('193.0.1/24') or die (Net::IP::Error());
print ("IP  : ".$ip->ip()."\n");
print ("Sho : ".$ip->short()."\n");
print ("Bin : ".$ip->binip()."\n");
print ("Int : ".$ip->intip()."\n");
print ("Mask: ".$ip->mask()."\n");
print ("Last: ".$ip->last_ip()."\n");
print ("Len : ".$ip->prefixlen()."\n");
print ("Size: ".$ip->size()."\n");
print ("Type: ".$ip->iptype()."\n");
print ("Rev:  ".$ip->reverse_ip()."\n");

但我得到了：

rr@sd-562 # perl tmp.pl
Can't locate Net/IP.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at tmp.pl line 1.

我在网上也没找到什么有价值的东西。
