New nodes have two numbers assigned to their wireless interface,
169.254.a.b/16 and 10.0.x.y/32.  [32 is not a typo. :-)] Old nodes have
10.0.x.y/16.  The SSID switch happened a little bit before the IP switch.

That is probably the city node changing its BSSID.  It has been known
to do that.  The MACs will stay the same.

On the private wiki, yeah.  In the interest of folks' privacy, I try to
keep that info out of the public domain.
