I just logged onto idd.cise-nsf.gov as 'ldm' and ran a traceroute back to idd-ingest.meteo.psu.edu: /opt/ldm% traceroute idd-ingest.meteo.psu.edu traceroute to idd-ingest.meteo.psu.edu (128.118.28.130), 30 hops max, 40 byte packets 1 cise-7204-1 (192.12.209.1) 0 ms 60 ms 235 ms 2 arlg-nsf.maxgigapop.net (206.196.177.137) 1 ms 1 ms 1 ms 3 xe-7-2-0-0.lvl3-t640.maxgigapop.net (206.196.178.90) 4 ms 7 ms 3 ms 4 i2-lvl3.maxgigapop.net (206.196.178.46) 2 ms 3 ms 3 ms 5 beast-internet2-gi2-0.3rox.net (192.88.115.24) 15 ms 10 ms 10 ms /opt/ldm% traceroute -n idd-ingest.meteo.psu.edu traceroute to idd-ingest.meteo.psu.edu (128.118.28.130), 30 hops max, 40 byte packets 1 192.12.209.1 0 ms 0 ms 0 ms 2 206.196.177.137 1 ms 1 ms 1 ms 3 206.196.178.90 2 ms 2 ms 2 ms 4 206.196.178.46 3 ms 2 ms 2 ms 5 192.88.115.24 10 ms 9 ms 10 ms The lists are abbreviated because the traceroutes hung (or, at least, did not continue for the 5 minutes I waited).
