perl程序:判断ipv4或ipv6

一个判断ipv4或ipv6的perl程序:

more 1.pl

#!/usr/bin/perl
use Net::IP::Checker qw[:ALL];
 
my $ip = '172.16.0.216';
ip_is_ipv4( $ip ) and print "$ip is IPv4\n";
 
$ip = 'dead:beef:89ab:cdef:0123:4567:89ab:cdef';
ip_is_ipv6( $ip ) and print "$ip is IPv6\n";
 
print ip_get_version( $ip );

直接执行会报错,没有相关模块。

要先安装cpanm 这个利器:
yum install perl-App-cpanminus.noarch

安装所需模块:
cpanm Net/IP/Checker.pm

再次执行:
[root@centos7 perl]# perl 1.pl 
172.16.0.216 is IPv4
dead:beef:89ab:cdef:0123:4567:89ab:cdef is IPv6
