sites,
versus actual maps of the networks in question? Most tier 1 ISPs

even let their vendors see the latter.

I had a look at your map of Ebone Europe through the browse button on your
website. This displayed a messy meshy network that connected all the major
cities of Europe. However, in fact, Ebone's network was a nice clean
ringed network connecting all the major cities of Europe. It's true that

understanding of routing (especially inter-domain) in the research
community is really primitive. this precludes us from having realistic
routing models. we recently started working on understanding prevalent

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
I'd like to second this. We have ran in to problems as well. Usually
this is a great place to get help however we have had very responsive
actions taken by others out there who had filters in place.

We feel your pain, Scott. We are just glad that we are able to verify that there are
problems with this CIDR other than on our network.

It is not clear if you mean that tools (e.g. BGP) are

Try finding some IP connectivity while in Nigeria. You would be
hard-pressed, even if you are willing to pay enormous $$.

Who cares? It's not like one of you got ripped off by 419. Load up
SpamAssassin and forget about it. Kinda sad how a thread that
started about finding networkers in Africa turns into derogatory
remarks about countries you have no clue about.
Shut up and move along.
