  We model the insulator neighboring the 1/k quantum Hall phase by a random
network of puddles of filling fraction 1/k. The puddles are coupled by weak
tunnel barriers. Using Kirchoff's laws we prove that the macroscopic Hall
resistivity is quantized at $k h/ e^2$ and independent of magnetic field and
current bias -- in agreement with recent experimental observations. In
addition, for k>1 this theory predicts non linear longitudinal response $V\sim
I^\alpha$ at zero temperature, and $V/I\sim T^{1-{1\over \alpha}}$ at low bias.
$\alpha$ is determined using Renn and Arovas' theory for the single junction
response, and is related to the Luttinger liquid spectra of the edge states
straddling the typical tunnel barrier. The dependence of $V(I)$ on the magnetic
field is related to the typical puddle size. Deviations of $V(I)$ from a pure
power law are estimated using a series/parallel approximation for the two
dimensional random nonlinear resistor network. We check the validity of this
approximation by numerically solving for a finite square lattice network.
