Using the Chalker-Coddington network model as a drastically simplified, but universal model of integer quantum Hall physics, we investigate the plateau-to-insulator transition at strong magnetic field by means of a real-space renormalization approach. Our results suggest that for a fully quantum coherent situation, the quantized Hall insulator with RH approximate to h/e(2) is observed up to R-L similar to 25h/e(2) when studying the most probable value of the distribution function P(R-H). Upon further increasing R-L --> infinity, the Hall insulator with diverging Hall resistance R-H proportional to R-L(k) is seen. The crossover between these two regimes depends on the precise nature of the averaging procedure.
