There are two parts. Those that one can deduce becuase of the data and those
things one can guess as patterns of names.
Starting with your gateway.
1 CYH-A100-VLAN10.GW.CMU.NET (128.2.10.254) 1 ms 1 ms 1 ms
CMU.NET is assigned to Carnegie-Mellon University (which has the
128.2.0.0/16 class B network)
From the name CYH-A100-VLAN10.GW, I would guess you are on a switched 100
Mb/s virtual LAN. and this is its gateway. The speed response indicates this
as well.
2 RTRBONE2-FA4-0-0.GW.CMU.NET (128.2.255.1) 1 ms 1 ms 1 ms
This has a fast ping and seems to be a Router backbone at the
University, probably the Universities firewall
---->now leaving Carnegie-Mellon
3 beast.psc.net (198.32.224.253) 1 ms 1 ms 1 ms
This your Internet2 access at Pittsburgh Super Computer Center.
4 abilene-psc.abilene.ucaid.edu (192.88.115.121) 4 ms 4 ms 4 ms (this does
not have a forward public DNS entry)
ucaid is University Corporation for Advanced Internet Development another
part of Internet2
It is based in Ann Arbour Michigan
5 nycm-clev.abilene.ucaid.edu (198.32.8.30) 17 ms 16 ms 17 ms
Routing within UCAID (probably to Cleveland) but now on a slower speed link
6 abilene-stm4.ny4.ny.dante.net (212.1.200.153) 17 ms 17 ms 16 ms
dante is the ISP arm of a European Research Consortium (this looks like the
New York end of a Trans Atlantic cable)
7 ir-nyc1.g-win.dfn.de (212.1.200.50) 17 ms 17 ms 17 ms
This is New Your peer from Dante to dfn.de (on same subnet as dante.net one
so may be in same closet).
dfn.de is Verein zur Foerderung eines Deutschen Forschungsnetzes (DFN) e.V
(for German Universitys)
8 cr-frankfurt1.g-win.dfn.de (188.1.18.53) 125 ms 125 ms 126 ms
This is your trans-Atlantic hop to Frankfuurt
9 cr-muenchen1.g-win.dfn.de (188.1.18.26) 125 ms 125 ms 125 ms
To Munich window on German high speed network peering point
10 cr-hamburg1.g-win.dfn.de (188.1.18.30) 125 ms 125 ms 125 ms
To hamburg peer (seems to be a bit of an odd route here).
11 ar-oldenburg1.g-win.dfn.de (188.1.92.34) 127 ms 127 ms 126 ms
Gateway to Oldenburg University connection to dfn
12 cata-ol1.hrz.uni-oldenburg.de (134.106.254.1) 128 ms 129 ms 128 ms
One of the many gateways to Oldenbburg University (probably a Cisco
Catalyst switch)
Oldenburg University also has a class B network so all the 134.106.x.x IP's
belong to them.
13 cisco-ol3.hrz.uni-oldenburg.de (134.106.201.2) 128 ms 128 ms 128 ms
14 cisco-ol.hrz.uni-oldenburg.de (134.106.49.8) 131 ms 129 ms 132 ms
15 cisco-oss1.hrz.uni-oldenburg.de (134.106.34.254) 135 ms 132 ms 136 ms
16 cisco-oss2.ossnet.uni-oldenburg.de (134.106.143.2) 139 ms 147 ms 143 ms
Routing within the Oldenburg University network (from times looks like a
10Mbs Ethernet)
17 134.106.143.6 (134.106.143.6) 141 ms 148 ms 145 ms
Hits a blocked route within the University. Probably your ping is being
dropped by an internal firewaALL OR SCREENING ROUTER.

Subject: analyzing traceroute ouput
how much info can u glean from this traceroute output?
what does it tell u about the network devices being used?
does it tell u anything about the routing technologies?
