Operational Issues with 69.0.0.0/8...

Thanks for the reply, James.

I wish I could tell you the answer.  We see traffic passing through some
of the routers (transit), but on each network, or their downstreams
there seem to be different devices filtering.  Sometimes it is a border
or peering router.  In other cases, it has been access devices, such as
firewalls.

One we resolved this morning (with some help from the good folks at
ARIN) was a downstream provider from one of these transit providers that
was filtering in their devices as well.

I am just trying to raise general awareness that the 69.0.0.0/8 block is
assigned and out there in use, and to get people to re-examine their
filters, access lists, etc.

You help and response is appreciated.

Sincerely,

When you say 'Networks involved' do you mean those providers are
blocking
the traffic, or you see these networks in the transit?

Thanks,
James
