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.
