I was trying the other day to do a traceroute on
I tried doing this from a couple of different sites (found @
www.traceroute.org) and they all exhibit similar behaviour: when connecting to
www.nasa.gov, instead of connecting to one of nasa.org's cannonical names, it tries to connect to another IP address, generally from the same country the traceroute site I'm using is from. Even worse, it seems that for each country there are a couple of different IPs associated with
traceroute to www.nasa.gov (22.214.171.124), 30 hops max, 40 byte packets 1 gx-kmi-e1-a.mdn.nusa.net.id (126.96.36.199) 0.266 ms 0.265 ms 0.432 ms 2 gw-kmi.mdn.nusa.net.id (188.8.131.52) 1.430 ms 1.433 ms 1.416 ms 3 184.108.40.206 (220.127.116.11) 32.137 ms 32.143 ms 32.149 ms 4 18.104.22.168 (22.214.171.124) 32.155 ms 33.083 ms 33.069 ms 5 icore-sgp.ge-1-3-0.bb.xl.net.id (126.96.36.199) 130.189 ms 188.8.131.52 (184.108.40.206) 130.134 ms icore-sgp.ge-1-3-0.bb.xl.net.id (220.127.116.11) 130.178 ms 6 tm.net.my (18.104.22.168) 65.494 ms 66.277 ms 66.039 ms 7 22.214.171.124 (126.96.36.199) 64.707 ms 64.693 ms 65.792 ms
188.8.131.52 is an IP from malasya.
At first I thought this could be related with mirrors, but I am not so sure now. Even for trace sites of small countries, it seems there are several IPs, and I have my doubts that a site such as
www.nasa.gov generates that much traffic to need to be replicated on so many places, even for small countries.
What is the reason of this? Is my racionale wrong?
