Being curious, I did some pinging from my direct net-10 host, SCCGATE.SCC.COM (10.11.0.20). It has its DEFAULT route set to PURDUE-CS-GW.ARPA. I ping successfully off of FUZZ.CSC.ORG (128.121.50.20) JVAX.CCIT.ARIZONA.EDU (128.121.50.100) JVAX.CCIT.ARIZONA.EDU (128.196.1.1) NOAO.ARIZONA.EDU (128.196.4.1) I could not raise a response from NOAO.ARIZONA.EDU (192.31.165.2) for quite some time. I made a number of attempts over a 10-15 minute period. I found this curious, as this is simply the address on the 192.31.165 network for the machine I had just heard from using the 128.196 network. Further, I had initially been unable to raise any hosts on 192.31.165, and after I started to hear from the 192.31.165 side of NOAO.ARIZONA.EDU, I also found that I could reach those back hosts, but the ping echo times were much longer than those obtained from the 128 addressed gateways/hosts. I checked my routing table. Here is what I found. destination net gateway 128.121.0 psc.psc.edu 128.196.0 psc.psc.edu 192.31.165 DCEC-MILNET-GW.ARPA It appears that I'm routing through a MILNET gateway to reach net 192.31.165. Hope this info can be of some help to you, Bob ------
