How To Ban A Specific IP From Accessing Your Site With PHP

[Gaijin]

Thanks for the words of advice Gaijin, if I ever actually use this myself I'll definitely do it that way. But, isn't the hostname the pipeline? Therefore it would block anyone within the same area as him?

True, but as far as I know ISP generate hostnames for a connected system, therefore each system having unique ip within the hostname... I'm not really sure about this... But..

I have 3 laptops, all share same hostname, where my neighbor (having the same ISP) has a slightly different hostname, so blocking my host name, would disable all my 3 laptops from accessing the site, while my neighbor would be able to access it since hist host name differs from mine slightly...

I'm not really sure about that, I have tested it only with me and my neighbor...
