1) Could you configure your routers w/ secondaries to "answer" for the 1918 space the phones are looking for? What happens if the phone actually gets an answer? A) Will it shut up, or B) can you use this to get more diagnostic information?
We could; the addresses have all been different so far (10.0.1.1, 192.168.1.1, 192.168.2.1) .. we haven't tried during an active problem so far but will.
2) I wonder if they hacked in some special sauce roaming ability? It seems like what you are seeing may be aggravated by the device roaming between ip subnets but staying on the same SSID?
Perhaps, yes. We know anecdotally that some people use the same SSID at home as on campus for ease of use. Though the iPhone yesterday apparently did not fall into this category.
So could they implement a way to deal with the case where a user would roam from ap A to ap B staying on the same SSID. So maybe they chose to self arp to help populate upstream bridge tables, but they accidentally reuse stale cached ip info?
Perhaps, though I'd hope the algorithm was setup to try, wait, timeout after some period of time.
