> If you have a properly configured firewall why is it problem? Especially given the massive address space. Privacy? Security? Do you really need the whole outside world to know how many computers are on your network, and which one is browsing which sites or doing what exactly at which time? Most people don't, for privacy reasons... and if an attacker can single out a particularly sensitive computer to target, then that becomes a security risk too. If it's avoidable then you avoid it, it's as simple as that. EDIT: I don't understand these random downvotes. The concern actually exists, that's why (as one comment pointed out) people have been proposing privacy extensions to IPv6. What in the world are people downvoting? You don't like reading facts?

You're likely being down voted due to your attitude. It's one thing to politely argue a position, quite another to ask rhetorical questions as though everyone else is stupid for not knowing the obvious.

  Thanks for explaining, but what attitude are you seeing in the first [1] post? In this one I was annoyed at the downvotes on the first one and (later) this one, but what was wrong with the first one? People downvoted it for no reason... this seemed just a continuation of that.

    That post seems fine. I'm not sure why it was downvoted. If it makes you feel any better, some of my comments get downvoted too, especially in the first hour or so. Then over the next 24-48 hours the scores will go up again. The worst thing to do is complain about the downvoting, though, because that pretty much forecloses any chance of recovery.

People aren't proposing privacy extensions, it's a finished standard that's been enabled by default in most major operating systems for many years now.

  > People aren't proposing privacy extensions, it's a finished standard that's been enabled by default in most major operating systems for many years now. Apparently [1] it's not that simple, and apparently [2] stuff came after that standard in as late as 2014 (and I can't really say I've been keeping up with IPv6 news enough in the past 3 years to know how things look different right now compared to 2014). I also see a related Defcon article from 2015 [3] which claims "IPv6 is bad for your privacy" though I haven't read it yet.
