@miki @sindarina I think the whole point of this thread is that 1.2.3.4 does *not* make it obvious that the address is an example and needs to be changed. That's somebody's real IP address. And yes, I understand the reason why you're making this argument, that 1.2.3.4 looks made-up in a way that 192.0.2.4 does not, but that only lasts as long as nobody tries connecting to it (which realistically is not likely to be the case for long).
