It's not a subject I know very much about. My technical knowledge doesn't extend that far. Certainly I know that you can identify the IP address of anyone accessing your site. However an IP address isn't unique to an individual but to the ISP they're using. So if a hundred people all using the same ISP came here, they would all show up as having the same IP. So in theory we could probably prevent someone using a particular IP address from accessing the site. However this wouldn't really work for several reasons. 1) You wouldn't be blocking one person, but possibly many hundreds or thousands of people 2) Even using the same ISP people will often be assigned a slightly different IP address everytime they log on to the internet. So the IP address you have today could be different from the IP address you have tomorrow. To my knowledge, IP blocking is only effective if you want to block out an entire bunch of people. like say if you're China and you want to block your citizens from accessing large parts of the internet. Hope that makes sense. Andy Quote |
