Hi there, Here's an interesting one for you guys, I work P/T at a Local Authority ISP service based upon open source code. The kids Have recently realised that is you take www.playboy.com convert it to it's IP 216.163.137.3 covert it to Binary 11011000 10100011 10001001 00000011 then back into base 10 decimal 3634596099 now you enter this into your browser http://3634596099 at first I was unsure if this was an april fools but sure enough it works and bypasses the filtering completly. Not many sites work but I did find one or two more. Both url blocking in squidguard & IP filtering does not effect base 10 Has anyone any idea how we can get squid to ignore Base 10 & Hex web requests? kids will be bypassing filtering platforms up and down the UK (or more probably have been for some time) credit to them, clever little blighters
