some addresses unreachable Some addresses are unreachable through nlams05. For instance:
Tracing route to 2001:da8:200:900e:0:5efe:166.111.64.176 over a maximum of 30 hops 1 * * * Request timed out. 2 * * * Request timed out. 3 * * * Request timed out. 4 * * * Request timed out. 5 * * * Request timed out. 6 * * * Request timed out. 7 * * * Request timed out. 8 * * * Request timed out. 9 * * * Request timed out. ..........
Meanwhile, for some other addresses like www.ipv6.org, it works fine:

some addresses unreachable
[ch] Jeroen Massar SixXS Staff on Sunday, 18 October 2009 16:25:24
Some addresses are unreachable through nlams05. For instance:
Tracing route to 2001:da8:200:900e:0:5efe:166.111.64.176 over a maximum of 30
hops
That is an address somewhere in China, most likely even located behind an IVI gateway. Your traceroute does not even work locally.

On the other hand, at the same time, by using nlhaa01, the first unreachable
address through nlams05 can be reached:
