Hi folks, just stumbled (literally!) onto this site and it is very very useful for finding IP ranges for blocking if necessary. Please read the FAQ on the site as it does answer a few questions! But be warned, you do this wrong and you could potentially block an entire counrty (and yourself!!!) from accessing your site or server!

Please note, only use these for blocking if you know what your doing! If you don't, ask here and the experts will hopefully be able to advise you (nice bit of publicity for the brains of the operation <img>)
