There is no way to know conclusivelly whether the final address is dynamically or statically assigned. Based on the information you have given there is no definitive way to tell. In many ISP situations, you'll see a static route added to a core router that points to a modem bank which then assigns ip's to dial-up users as they are requested. So, a loop like the one that you describe could be either a dial-up rack that has a static route pointing to it, or it could be any number of other things. Though if the traceroute looks like it's pretty close to the edge of a network, you might be inclined to suspect dial-up. What you really want to do if you suspect wrongdoing is to fire off an email to abuseat_private and find out what the address is assigned to. -mp * Burnette, Michael (MWB@rh-law.com) [030526 08:27] spake thusly: > What would explain the following scenario (or what if anything would this scenario tell you about the machine in question): > > 1) A traceroute to a public internet address times out at 30 hops.
