Re: Checking bogon status of new address space

Having recently received some de-bogon'ed addressing in or about this March,
I can tell you that the one problem I had was people that had not updated
their Bind Bogon filters (
http://www.cymru.com/Documents/secure-bind-template.html) and so were not
responding to requests from our address space, so we just moved our dns
cache boxes back to our older Level3 address space.  Took a while to figure
that one out though.

Hi,

my company has just been allocated some new IPv4 address space, and I want
to do some sort of automated testing to find out any ASs out there that
haven't removed the /8 it's on from their bogon list (the allocation to our
local registry only occurred in November last year).

Has anybody attempted to do this? It is worth bothering? Currently I'm
considering pulling out all the endpoint ASs out of the BGP table, finding
at least one subnet for each of them and attempting to ping or reach other
common ports on a single IP for each AS from our currently working
address space, and then the new address space and comparing results.
