All bar one (which is in a different > originated AS) of ours are in the same /24 (different /30s, and > different continents in some cases). Most "real" providers have diverse nameservers. For them, this is not a problem, but for the other 99% of domains that are delegated, they have their nameservers on the same ethernet segment. Domain Name: MONICALEWINSKI.COM Domain servers in listed order: ZORK.TIAC.NET 199.0.65.2 SUNDOG.TIAC.NET 199.0.65.9 This means once your /24 drops from routing, you have no primary nor secondary nameservice. This is meant only as an example, but to make my point. Because the delegation authorities can do an easy check to see if the ips are in the same /24, this could prevent a number of real outages, such as a TLD being OOS, but also help fix all the little guys who don't understand the idea of geographicaly diverse nameservers. - jared -- Jared Mauch | pgp key available via finger from [email protected] clue++; | http://puck.nether.net/~jared/ My statements are only mine.
