There is a packet flux for packets being transmitted to 128.8.26.90. Hmm.. I think, this is pretty strange. TERP.UMD.EDU, which is one of the root name servers, has an address which is fairly similar: 128.8.10.90. I guess that the bogus address is the "MILNET" version of TERP's "ARPANET" flavored address.. Really weird. Bouncing name server queries to the hosts in question indicate that they have an incorrect idea of what TERP.UMD.EDU's IP address is. Will you all please take a look at your root name server cache infomormation, and make sure that you have correct information? I suspect that these bogus packets and the associated ICMP destination unreachable messages are using a non-trivial amount of bandwidth between the US and Europe. Let's try to track this down before it spreads very far. I'm seeing a few packets per second being transmitted to the bogus address. louie
