Bingo!

I'm not sure, but reading netmasks(4) I don't think so. Note that it has an example entry: 128.32.27.16 255.255.255.240 and says that the system uses the longest prefix found. OTOH, I don't immediately understand how the example can work. It says that 128.32.*.* (except for the exclusions) gets a 24-bit netmask, but I don't see how that can be unambiguously determined. The example *seems* to want to explicitly specify a 28-bit netmask for several ranges and a 24-bit netmask for the rest, but how can it distinguish between requesting that 128.32.*.* is all 24-bit and requesting that 128.32.0.* is all 24-bit? (For that matter, why isn't it specifying that 128.001?????.*.* is 24-bit?) > Although I do suggest that specifying the prefix > length (such as /24) via zonecfg(1M) is the best solution. Point-specifying a global value seems like the wrong answer. Normalization says that you should specify the global value in one place, not replicated across many. (Less abstractly, that you should specify the netmask in one place, not individually for each address that uses it.) _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
