Hi list,
I can't seem to find any tools that'll aggregate a list of IPv6 prefixes.
Used to 'aggregate' for IPv4, looking for something similar for IPv6.
Thanks!
Looks like the most recent NetAddr::IP perl module will do it:
http://search.cpan.org/~miker/NetAddr-IP-4.059/IP.pm#EXPORT_OK
Take a look at the Compact function. I think that's what will do it.
--chip
Found this tool that works perfectly.

Hoping this'll help someone else here on the list. Thanks!
The Net::CIDR package contains functions that manipulate lists of
IP netblocks expressed in CIDR notation. The Net::CIDR functions
handle both IPv4 and IPv6 addresses.
Thx, this is at least three times faster than what I have here.
Just a comment on the final print statement, which doesn't fit my needs
for ipv6:
- print "prefix: ", $_->prefix(), "\n";
+ print "print: " , $_->print(), "\n";
- prefix: 2001:0db8:0000:0000:0000:0000:0000:0000/32
+ print: 2001:db8::/32
Rgds, Stefan
thanks! Was wondering how to do that.

$ perldoc Net::IP 
That doc's a fine one to read also for other
reasons.
Cheers,
