internet blocking problem ?

^^^^^^^^^^^^^^^^^^^ Well, to be precise 'Cogentco was the last node on the route which responded'. It's impossible to say whether i) that node tossed packets that tried to go further; ii) it forwarded them to some other node (identity unknown) which did toss them (and didn't allow/handle traceroute), etc. One can't draw any conclusions about whether it's i) from the fact that it's _also_ still responding to traceroute packets sent to that address: one would have to know whether it does the a) 'is this packet to a destination I'm filtering' check before it does the b) 'I decremented the TTL and it's now zero', or the other way around. If b) it could be the node that's dropping the packets. But given that other 'last hops' are also producing similar results, I'm still thinking it's Ii.net which is tossing the packets, not the 'last hop' one can see on traceroutes. Noel
