Re: [nznog] Tools for automatically summarising CIDR notation list?

Many thanks Tom (and Michael and David - offlist) David, I'd love a copy of the Perl script to do it, but in the meantime, I used some better search terms from the replies so far to actually find an online converter that seems to do the job. http://forums.modem-help.co.uk/aggregate.php Thanks all Cheers _ N On 6 June 2014 13:42, Tom Paseka wrote:

This one is magic :)

My Google-fu has failed me. It defies logic that there aren’t tools (application, Excel based or online) which will take a list of CIDR formatted prefixes and spit out an optimally summarised list also in CIDR notation. I however, can’t find them.

Neither can my friends.

I have seen an excel sheet which almost does it, but it requires significant manual interaction and I think it relies on zero point energy and/or wizards magic to work… and I don’t understand it well.

Any pointers?

And no, doing it in my head isn’t feasible J
