Hehe. Decimal -> binary in your head? I don't even bother except if
it's some well known "magic #s". Hex -> binary though is super simple
since unlike decimal, each digit translates exactly into a nybble. You
just have to know the binary from 0 - 15, 16 simple four-bit patterns,
and it's a piece of cake. You can give me hex numbers and and I'll
rattle off binary all day, or vica-versa. Octal is similarly easy, but
would result in some long IPv6 addresses. :-)
