Hello.
I've been DROP'ing the same list of IANA-reserved addresses (shown below)
for about 8 months, so I quess it's about time to revisit this list.
Manually comparing the current list
(http://www.iana.org/assignments/ipv4-address-space) and my list below, I
see that I should remove 219.0.0.0/8 from my list. Ok, done.
What I would really like is to automate this process so that it can be done
on a periodic basis. Sure, I can just grep the document from iana.org, but
I like the efficiency of having the list collapsed into fewer entries as
shown below.
Has any clever person done this get-list/collapse/update as a cron job? If
so, where can I find it?
Thanks.
