IMHO, the internic should not allow any domains to have pri+sec nameserver in the same /24Why not? I know several people who stick them all in /30s as they are so difficult to move. 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 jared () puck nether net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
