Sorry for the delay, I moved on to other experiments.
I had (and continue to) use the ONVIF Device Manager for probing information in the cameras. It works fine for video and most settings, though it gets unexpected responses when querying things like profiles.
Lack of complete discovery is not really much of a problem. In fact many of the programs I use are not very good at automated discovery of these camreas, sometimes picking up only one stream not both, sometimes just missing them.
My initial experimentation led me to believe it related to orientation (vertical vs horizontal) but that is not the case. There is something else going on, and I find it odd it is the first and last camera in the range -- that might be a coincidence, might not.
I would say of my experience this is more of a minor inconvenience than anything significant. If I get bored I will try swapping IP's around and see if I can find any pattern, whether it is specific to a camera or to the order it encounters the cameras.
It is worth noting that a debug log of some sort would be useful during this and other debugging, so one could look and see what actually happened, e.g. did it probe the address at all, did it fail to get authentication, fail to get a ping, fail to get http response, etc. Then I could tell you more precisely what happened. I did not note any way to get debug information logged -- is there?
