Thread:Project:Support desk/Easy way to implement massive IP range blocks?/reply (2)

Thanks. If I change the setting in LocalSettings after the block has been set, does the fix stay in or does it get lost? In other words, having now blocked 217.0.0.0/8, 218.0.0.0/7, and 220.0.0.0/6, if I set LocalSettings back to the way it was, will those range blocks still stay blocked?. What sort of collateral damage might occur (I have no Chinese users and don't expect any)?
