My results match Randy's. I looked at these blocks from several networks (ATT, Cogent, PSI, XO, Comcast). All have the routes showing. ICMP Echo packets do not come back via any of them. Either the machines aren't listening, the echos are being blocked, or there's widespread blockage. Traces appear to make it to Brazil before dying in all cases, pointing at an issue closer to where your test machines are located. At 01:24 PM 10/20/2005, Randy Bush wrote:
Commenting myself, there is an machine in the first address of each the announced blocks. Just in the case someone want to ping/traceroute. (189.0.0.1, 189.128.0.1, 190.0.0.1, 190.128.0.1) I forgot to mention this before.
