No coincidences with games like this. :)
(I went over it again, and of course a simple blob isn't just a binary, it has no magic bytes or anything, stupid.)
Using "Israel-is-70" gives me ... 3?.205.32.11
Which of course looks like an IP-address, but incomplete (the ? is C0). Probably made a mistake with the decoding of the key-part of the brainfuck. Still, only 10 numbers to pick from: 3[0-9].205.32.11
Edit: thanks to Seagull for pointing it out already, the key was off by one byte. So that gives 35.205.32.11
