first post that I stated a traceroute shows both IPs have the same last router hop and are likely on the same subnet.
Correct. Both machines actually do live in close proximity to each other.
Add to that the fact that there are load balancing techniques which use duplicated IP addrs in different geographical regions and you once again have no proof - just an implication.
Not that fancy. Not yet. If the internic would process get with it and process our update, it would show two additional nameservers on the domain however. (On different networks, which are in different geographical regions.)
Before anyone else pounces on this, YES, I believe it is likely that these two machines (if it is two machines) are sitting next to one another and the original poster should get more diverse DNS. The point of my post is

that people who just look at IP addresses (or a single traceroute ;) and make sweeping generalizations might find their assumptions disproven.
In this case, they were correct. I suppose they would have felt better if we had something like: NS1.ENTERZONE.NET 209.41.244.5 NS2.ENTERZONE.NET 209.41.222.129 NS3.ENTERZONE.NET 216.28.26.5 NS4.ENTERZONE.NET 209.115.110.130 NS5.ENTERZONE.NET 199.201.138.5 Sure does look more impressive, doesn't it. Sheesh people. The last time I checked, I wasn't providing primary of secondary name service for any of your domains. We've never been dark outside of scheduled maintenance, not even as a result of TIFF or BIFF. I feel very lucky in that statement. I suppose it is a testament to the guys at FNSI.
Sorry about being pedantic, but I've dealt with one too many users who just assume stuff based on tools like traceroute without understanding the underlying technology (asymmetry, load balancing, etc.). I really think anyone on this list should *not* have to be educated the way lusers do.
I was told by a wise individual that the only use for assumption is to make an ASS out of U and ME. From what I've observed, there are a few individuals on the list, myself included at times, that need no help in this category. Leave the assumptions, snide remarks about another operator having less than sufficient clue, etc out of it. Since we're talking about my nameservers and I've told you everything there is to know about them, there should be no more need for discussion of this matter on the list. ------------------------------------------------------------------ ML.ORG is gone.
