Hi, the procedural ip_reverse call fails with ipv6 addresses with shorthand :: for missing 0's. The OO reverse_ip method works. ~@ns0% cat rev2.pl #!/usr/bin/perl #use Net::IP; use Net::IP qw(:PROC); $v6addr='2001:468:1420::151'; my $ip = new Net::IP ($v6addr) or die (Net::IP::Error()); print ("OO Rev: ".$ip->reverse_ip()."\n"); my $revaddr=ip_reverse($v6addr); print ("Procedural Rev: ".$revaddr."\n"); ~@ns0% perl rev rev2.pl revip6.pl ~@ns0% perl rev2.pl OO Rev: 1.5.1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.4.1.8.6.4.0.1.0.0.2.ip6.arpa.

Perl is good at handling processes and files, and is especially good at handling text. Perl's hallmarks are practicality and efficiency. While it is used to do a lot of different things, Perl's most common applications are system administration utilities and web programming. A large proportion of the CGI scripts on the web are written in Perl. You need the perl package installed on your system so that your system can handle Perl scripts. Install this package if you want to program in Perl or enable your system to handle Perl scripts. ~@ns0% rpm -qi perl-Net-IP Name : perl-Net-IP Relocations: (not relocatable) Version : 1.25 Vendor: Red Hat, Inc.

Two applications using the Net::IP module are included: ipcount, an IP address mini-calculator, it can calculate the number of IP addresses in a prefix or all the prefixes contained in a given range; and iptab, which prints out a handy IP "cheat sheet". danno -- Dan Pritts, Sr. Systems Engineer Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224 Internet2 Spring Member Meeting April 26-28, 2010 - Arlington, Virginia http://events.internet2.edu/2010/spring-mm/
