Since you have experience, maybe there's something you can help explain with what was mentioned: > In fact, out of the 32 valid domain names that are 1-bitflip away from windows.com "windows" is 7 characters long so how is there 32 1-bitflip combinations? Also one of the ones mentioned was "windo7s", but "w" is 01111000 and "7" is 0000111, which isn't a single bit flip away unless I'm doing something wrong.

You can't consider all bit-flip possibilities, you have to consider only those which result in valid domain names. Flipping a bit which results in a w becoming a / will never result in a valid domain name, for example. Your bit math here is wrong (not sure why). > "windo7s", but "w" is 01111000 and "7" is 0000111 7 is 055 is 0011,0111 w is 119 is 0111,0111 2nd bit is flipped
