I still don't see the point. If there's a vulnerability that can be used to leak your LAN address, you want the leaked address to be as generic as possible. Something like "192.168.0.2" is perfect; a crazy 126.16.2.x address is unusual and could be used to fingerprint Anonabox users.
That and the semi-randomized SSID have been bugging me all day while I wrote that wiki entry. I simply can't see the logic in or reasoning behind those decisions.
I personally don't think that it's a good solution. Poor operational security can't be solved by misdirection.
